This is a quick calculator for the most popular PCB manufacturers for prototype PCBs.
Shipping is often approximated, usually UPS ground or whatever is least expensive. This software is also US-centric, costs may be different for Europe, Canada, Australia, etc.
These prices are current as of August, 2007
Since this is a really old project, and I'm not mainaining it anymore, I suggest checking out PCBShopper.com from Bob Alexander - a much slicker and more recent version of the same.
