I have an update for the PCB sources in the wiki, but it is denying me access to edit the page.
The specific page is http://www.ladyada.net/wiki/tutorials/l ... urers.html, the section is the DorkBot PDX section. The site has moved to http://Oshpark.com, boards are now always purple soldermask, gold finish. Orders are 2-3/wk, about 2 week turnaround. Still $5/sqin for 3 boards. There is also a medium run service, same board specs, $1/sqin 150sqin minimum, 10 board minimum. You have to email firstname.lastname@example.org for the medium run service.
