Best fab houses to send Gerber's?

This may have already been covered but i cant find a thread. http://www.pcbfabexress.com is the best i have found so far.I want to order an 8 channel board that is 10x16(160sq.inches)This would cost more than i want to pay so if i cut the board in half i can order them at 10x8(80sq. inches) each at $33.00 a piece at Pcbfabexpress.$66.00 i think is a fair price for the basis of 8 high quality mic pre's in a 1ru case. Although this is a fair price does anyone know of a better deal in the U.S.?

http://www.pcbfabexpress.com left out the p!oops!

Advanced Circuits is a great place. We even use them where I work.

Here's a link to their "Bare Bones" section for great prototype board prices:

I haven't used Advanced Circuits, but they have a free design check service. And if you use it, they'll even knock some money off the price of your order!

I use Advanced Circuits, and Imagineering (pcbnet.com), both do good jobs on near production prototyping. Imagineering also bids pretty well on production quantity stuff.

I also use Alberta Printed Cirduits for early prototype simple work.
