I ran across this place in my travels, and I figured I'd share the news. 
This is the cheapest place I've found that offers small quantity runs of quality printed circuit boards.
An interesting outfit, looks like a real handy place to know about. To give a test of the service, I fired off a couple of small orders, and true to the ads, the total price was really what they said! Free shipping in the US? How is that possible at those prices?
I did two boards to try different options, some of the recently finished DCS-RC Reset board, and a few of the LMS boards. I went with the thinner boards for the LMS to see what that got me. Note that you get a square inch for $5, and you get three boards, so it's really 1/3 of that. With free shipping, it's hard to imagine doing this much cheaper! You can order more in multiples of three, so I did six of the LMS.
The offer all sorts of stuff that you don't normally find with a cheap prototype board, slots, custom outlines, etc. Usually, you're much more limited in the design.
Their model is they take a lot of these small orders and combine them into large panels and manufacture it, then cut it apart for the individual shipments. I suspect they actually do three or four panels with a single copy of each design so they don't lose them if they have a process issue for one board.
I predict this may become my new favorite prototype board house.
