BatchPCB

A while back I needed to prototype some printed circuit boards and I stumbled across BatchPCB. I've ordered from them a couple of times and they are great.

The basic idea is that they put a bunch of boards together on one panel and send the whole thing off as one design to have made. It takes a bit longer than some of the other prototype board houses out there but it's much cheaper and the minimum quantity is 1. I found other places that were actually a little bit cheaper per board but they made you buy 2 or more boards.

Another thing that I really like about them is that they save your designs. Once you find one that works and you want to order a few more it only takes a couple of clicks. They have great tutorials on their site too.
