"I strongly recommend that you insist on the use of MIL -STD "Tefzel" insulated wire for your airplane"

I agree.  Most of you are probably already aware of this, but a good source for Tefzel wire is SteinAir (http://www.steinair.com/). They have a good selection (from 22AWG up to 2AWG) at reasonable prices.  They also sell RG400 coax at a good price.  Currently their RG400 is $2.05/ft, unless you get 100 ft or more then it's $1.85/ft.  Other suppliers that I spot check from time to time are as high as $4.29/ft.
