Recently, when working on cleaning up the wiring in my room with the new 1a2 stuff, I ordered a 50Ft M/F cable from http://www.deepsurplus.com/.
Overall, I was very happy, you can get a custom length of almost any cable or stranded. The woman on the phone was genuinely nice and helpful.
I would definitely buy from them again, (if I can ever afford it,) because they have a good operation going.

I buy all my cords from them.... I take a 25 ft 4 pair patch cord, cut it in half and spade the ends.... I have finally settled on gray for my general color.... I was having cracking problems with some of the other colors.... I also found some great deals this last year on 25 pair cat 5 cordage, end of the roll cuts were priced within my budget and were long enough for my wiring project. the keystone jacks are priced nicely too! was able to completely wire my home with telephone and internet through this source!
