Update:
I have ordered a variety of cables now in the past couple of weeks and Deep Surplus is one of the best at order processing and delivering. Quick and friendly and they give you some Skittles as part of your order.
You can buy a 1, 000′ of siamese cable for under $120!
500′ for about $65.
Punchdown blade 66 for $6
If Deep Surplus can keep up the good experience with customers they are not going to have any trouble keeping me as a customer. And they are local.
