I was just searching around yesterday for the same stuff. I found a site called the www.thebitcoinminingoutlet.com

I just placed an order for 3 cables, pretty cheap, plus they offer various sizes too.

i think it was 19cm, 25cm and 29cm. Plus i guess they are throwing in a free guide on how to setup a bitcoin miner.

And you dont have to deal with CHINA lol
