You could look into *TryStar Welding Cable*/ .Chris Dahl is the "coppercableman" on E/bay.Variety of Cable sizes/Colors/and Names printed on the jacket Free of charge.No Paper Liner.....instead aThin Neoprene Liner.
I've bought TryStar 1/0 and 4~ga.Cable off a Welding Supply place north of where I live.I like it.Than I bought some off Chris.No probs. and he's a decent guy.No "Walk on Water Attitude" Prices are good too.
I think there was a thread about him.Not sure which area but may have been the Wiring/Electrical page.Good Luck.
