I bought one back in June and still have it hashing on one of my scrypt rigs.
May not pay out much but the scrypt rig is running anyway so why not.

New miner to the boards.
I started with my CPU and GForce cards back in June.
Took the risk and invested in a KNCMiner - Mercury, it has been great, 130+ Gh/s since day one.  Made my money back in BTC.
Got my Dad involved and we are running 3 R9 290's in one box and a fourth R9 290 in a second box.
Running really nice with about 800Kh/s on each card.  Trying to make that $30/day mark by mining and selling.
Some days are great, like NET coin yesterday, some days are mine and hoard.

Been watching these boards on the regular and decided to sign up.
