I bought 20ga hookup wire from bob roberts... you can get 100 feet single color for 5.. or 100 feet, in 10 colors, for 7... (easier to trace wires with different colors)
I got the 10 pack.. and it works pretty well.. He said the solid wire of the cat5 won't work as well as the stranded hookup wire that he sells.. (i originally was going to use cat5, but decided against it after he convinced me not to)
anyway.. i figured 7 bucks for a cp isn't too bad.. why spend all the $$$ on the rest to cheap out on your wire.. heh
