I've used
PCBWay on many occasions.
PCBWay are high quality, fast, helpful and astonishingly cheap. They have a special prototyping service at
PCB Prototype only $5
For 10 pieces of double sided FR4, each board less than 100mm on a side, plated through, silk screened and coated.
USD 5. For 10 x 100mm square boards (or smaller). Madness!
Even 4-layer is cheap! (They go up to 14 layers) They offer a huge range of options, including HASL, ENIG and many other plating options, a large range of conformal coatings, different colours for silk screening, edge connectors, routed (non-rectangular) boards, different board materials and thicknesses, choice of via types etc
Big plus for me is the availability of SMD stencils too. They also have many other services around 3D printing and CNC etc..
Pricing is very very low, quality is high, delivery is fast and they're very helpful if your Gerbers are not right or you have questions.
Not made my own PCBs for years - just no point any more - sold all the Mega-UK kit: heated bubble tanks, UV boxes, wash tanks etc. and got rid of all the chemicals!
