I've found good wire on EBay at reasonable prices.  EBay sellers often 
have wire in smaller rolls.  I got some high-quality military surplus 
RG-176U coax and only purchased 25 feet.  You have to buy a 100-foot 
roll from Mouser, etc..  Here's a picture of the coax on my CGS Tube VCA 
module:

The cable looks copper in color, because the insulation is clear teflon.

I also found some100-foot rolls of really nice 22 gauge wire with high 
temperature insulation in different colors.  You do have to know what 
you're shopping for, of course.
