ughhh it seems that surplus stores have everything you dont need....first off none of the wires are coated. FAIL......second the highest resistance they had was 50 ohm per foot of 36 gauge wire (type unknown)....FAIL......second off the closest to usable they had was i think a nickel chromium resistive wire with .9 ohms per ft with i think a 20-ish gauge....but overall FAIL.
