Thanks for the tip on the nickel wire. I just picked up a Terminator-C from Stormy's (still in transit) and was wondering about an alternative to the pricey silver NR wire. Just got a 50ft spool of 30 gauge off eBay from Temco for $6.20 shipped.
In case anyone was wondering where to get resistance wire as well, definitely give Temco a shot. I've used them for almost all of my resistance wire (they were out of stock on a couple sizes and found alltronics on eBay as well, though it was still Temco brand wire), and their prices are cheap, wire is good quality, and shipping is fast!
