The following is a user-submitted list of PCB manufacturers. Your results may vary.
- This page lists "board houses" that take your custom PCB layout file and convert it to a custom printed circuit board (PCB) (ready for the next step: "assembly" adding parts). For "standard" prototyping PCBs, see stripboard and other techniques.
The Ladyada PCB Cost Comparison Calculator is a quick way to compare the (very roughly estimated) price of your board at many of the following fabs.
(FIXME: briefly mention the most relevant "capabilities": "preferred" and "minimum" trace width / spacing / via hole size / via pad diameter. Link directly to the manufacturer's "capability page" so readers can confirm these numbers for themselves. Boards that push the limit of manufacturability cost more than robustly designed boards that use preferred sizes.) For more details, see Submitting PCB's for fabrication.)
A few of these board houses do some automated DRC or manual checking (or both) before fabbing your board. If they find any issues, they email those issues to you and put the board on hold -- which typically delays the board a day or two. However, most people consider this a good thing -- they would rather have a board a day or two later than the quoted turn time, rather than a definitely nonfunctional board immediately.

preferred: 10 mils min drill hole diameter 6 mil trace/space
Can go to 10 mil drill and 5 mil trace/space and still get "no touch" service (very modest price increase) Also can do outlines with up to 16 edges.
Has free BetterDFM service to check a design before fabbing.
Has a "will-call" pickup option if you live in the SF Bay area. This is nice because it cuts a day or two off your overall fab time
One disadvantage of Sierra "no-touch" is that they have a surcharge if you go over their hole density limit. (haven't seen this with other fabs) if you have more than 50 holes per square inch - their automated system doesn't let you place the order - you have to have someone manually add a $10 surcharge per board to continue.

All orders submitted before noon ship the next day. UPS ground shipping is free. Since they are located in the Portland, OR area this means you can get a board overnight to most places in the Northwest US.
Basic service is a two layer board routed to any size and shape. Two 9 sq inch boards for $63 (including shipping). Soldermask and silkscreen doubles the price.
EAGLE CAM export and design rule check scripts are provided.
PCBexpress is apparently a division of Sunstone Circuits Quickturn service.
5 Boards for $60 ($12 ea. for 10 sq. inches) with a 5 day turn time.
2 boards, 2 layers next day shipping for as low as 7.95 each. or 2 boards, 2 layers, 2 solder masks and legend one side for as low as 9.95 each. 3 Day Service

Full CNC contour routing including plated slotting, oversize holes, internal cutouts for a modest fee
Instructions for creating Gerber and NC output from many popular PCB programs are also on this site.
4 2 layer boards for $19.89 each. Great prices for production board runs. Helpful staff.
- minimum 0.004" (0.1 mm) trace/space
- minimum finished hole size: 0.008" (0.2 mm)
- Very low cost quick turn proto promo prices too
Free proprietary schematic and layout software, used for all board services (like PCB123). Simplifies the process of getting a board done and out, by vertically integrating the design and production flow. Fewer options and less power, but fewer ways to screw up.
- Good deal on small prototypes: Mini-Board Service (3 identical boards, 2.5" X 3.8", doublesided, plated through, no silkscreen or soldermask) is priced well at $51 total, plus $10 shipping. Orders placed by 2PM ET ship the next business day by 2nd Day Air.
- Capabilities(inches) Production: Minimum trace width: 0.006". Minimum clearance: 0.006", preferred 0.010" . Perimeter clearance: 0.015", suggested 0.025". Holes - 23 sizes: 0.014"(via only), 0.020" - 0.251". Minimum Hole Spacing: 0.021" between edges. Vias/holes: 0.031"/0.014" -0.115"/0.052" . Pads/holes(round/square): 0.041"/.020" - 0.450"/0.251" . SMT: 0.010"x.070" - 0.420"x0.420" BGA: 0.012" - 0.020" .
- Software features: SCH netchecks. PCB imports PADS netlists, and illuminates nets nodes to assist in connection. Built-in updated price quotes for all offered board services. Copy to clipboard available for schematic & silkscreen+pads(layers must be screen-captured.) Pretty good selection of components, pads, symbols, for free.
- Notes: No Gerber support. Primitive single-level undo/redo. No PCB footprint selection/placement wizard from SCH info. No autorouting. SCH generates BOM, but PCB can't back-annotate (frustrating because most PCB footprints have Digikey part#s.) No net-based vendor integration. No scripting or plugins integration. Not enough keyboard shortcuts, uneditable.
- Review: The company is responsive and responsible. The Mini-Board service is addictively cheap and fast, and the other proto and production services are good, if not the cheapest option. Board quality is high; fine traces held up perfectly. The software is stable and simple, but tedious work for high parts-count or high-density boards.
- Conclusion: The sweet spot for ExpressPCB is sparse, simple, quickly-designed boards, at low and very high quantities. At any other density or complexity, might as well learn and use Eagle or KiCAD.
Turnaround ~8days + shipping, instant online quotes. $30 tooling fee, under $2/sq in.

Hobbyists created studio with PCB/PCBA services, they have outstanding communication among Chinese. They have some $10 offer for rather small board (5x5cm) or $25 for 10x10cm. A very good alternative if you don't need it in a rush, or in large volume. Eagle files are accepted too.
They started out with interesting ideas about open sourcing designs and them distributing the bare boards to other hobbyists: "An idea about open source PCBs", but this service has stopped.

Prototyping service does not include any manner of panelizing. The only post-submittal processing the Gerbers will receive is a basic DRC, mainly for things like silkscreen on pads (overlap will be removed automatically). Panelizing to fill out the 50sq-in board must be done prior to sending Gerbers. Jet will only route out the perimeter shape of the panel, and they do not score the boards, so separating out the individual boards must be done afterward by the purchaser. However, the perimeter can be nearly any shape, as long as it stays within the 50sq-in restriction.
