I discovered ZpoolMiner based on Nicehash miner couple of day ago and I like it.
Automatic GPU mining at http://zpool.ca/
Payout in BTC or LTC, set currency in worker name
12min mining fee every 12hours
Install , set payout , benchmark GPU and mine.
I speed up benchmark by cut and paste results from first GPU to all others.
