Anyone know where I can buy this in bulk at a good price? I got some from Bluejeanscable to try and it seems like good stuff. The problem is they charge about 3 times what I can get it for in bulk from other US suppliers and I need 120 to 150 feet. I was thinking of buying a 500 foot reel, 1000 is a bit much but if others are interested, we could split it? Thanks!
