Sorry for the lat reply. I've checked both those places and their wires are for home use with not much of a selection in the lower gauges. Plus the wire contain the minimal strands in all the gauges to make it slightly flexible. Radio Shack was a step down from Fry's... Since then I've found what I'm looking for by accident. If anyone is interested, here are the sites I've found:http://www.newark.com/http://www.digikey.com/http://www.mouser.com/
These site also provide other electronics components you may need.
