OmniUSB - further boards to make

My dad shops out prototype PCB manufacturing to a firm called Omnitrace ( He sends them layouts and they send back bare boards
which he stuffs in the lab ... He says the price is the best he's found,
there's no minimum run size (not sure on the plated edge connectors,
though) and the turnaround is very quick. He had samples of I think an
8-layer board they had done for him recently that he showed me last time we
visited and they were very nicely done. I haven't gotten to the point of
doing layout yet ... all my projects are still on the bread board ... but
when I do eventually run off some boards, I expect to use those guys.
