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