onlinemetals.com seems really good.

thanks guys! also, im trying to figure out what size of copper to buy. i was thinking either 1/4" x 2.5" or 1/2" x 12.5".

im looking at doing a simple block, probably either spiral or #rotor.

it looks like 1/4 is better if i am drilling both sides, where as 1/2 is better if i am only drilling one side. what is everyone else using? thanks.
