PCB manufacturers

OK, after making a successful prototype, does anyone have any comments on good or bad experiences with commercial PCB fabricators that are good for small volume? I just had a HORRRIBLE experience with e-teknet. Their prices are good, they made a few good boards for us, including some 6-layer boards. Then, I had a fairly easy 6-layer board that I ordered on Dec 4, 2003. I got the first batch of 7 boards on Dec 28, 2003, and discovered they assembled it with the layers in the wrong order. It took them 2 weeks or something to decide they were responsible, and I got a second batch of 5 boards on Feb 22. These boards worked fine. But, I ordered 12 pieces. Finally, after about 15 phone calls, they sent 5 more boards on March 24. After building one up, it was clear they did NOT test the boards, as I had requested in the order. I consider that THE cardinal sin, not testing, and supplying forged documents. It took me something like 10 hours to chase down the shorts. One was easy, the other was deep in the board, and I had to burn it out 3 times, as the short jumped from one power plane to another. I had good luck with Advanced Circuits, but their prices are pretty high, and I'm hoping I can find a reputable fabricator that can do it for less. (And, no, I DON'T have the technology to do 6-layer prototype boards myself. I do 2-side no plated through protos with a homemade laser photoplotter and dry film photoresist, though.) If there is a better list to exchange this sort of info, please let me know.) Thanks, Jon
