It depends just a little bit on the exact spec, but the stuff you typically see for sale cheaply on the surplus market isn't good a good "buy". Just my 2 cents as usual.

In this case, it's worth a whole dollar. Some of the veterans on the List will recall that Greg Richter came out in favor of Teflon in his treatise on foolproof aircraft wiring. See page 38 of: http://www.aeroelectric.com/articles/richter/response_1.pdf In my whole experience, I've only seen Teflon used for the flying leads of motors that operatee really hot . . . once the wires are outside the motor, they tied into Tefzel or similar. It's nice stuff to use as hookup wire inside an electronic assembly. The stranding is silver-plated and solders really nice! I've got a couple spools around here but haven't used any in years.
