I bought a miner piece from oneminer.com, who is a day-vendor of GAW products.  My piece was delayed, and oneminer.com hooked me up free with https://cloud.zenminer.com for the duration of the delay.  Only ONE pool was available to me, and that was BTC Guild.  Mind you, my piece was a BTC-only, not scrypt hardware, so my reply might be worthless to you.  But Hello! .
