yes I was running well on ghash until ghash crashed my s-3 auto- switched to a backup. The tube went dead so I joined www.mmpool.org and I thank you for mentioning it as a second option. In fact I am sticking with them as you get a bonus if you find the block.
Now an update to the controller for 2 pools with auto-switching would make things very nice for me. I found a location to mine that will charge me 6 cents a kwatt. I can only run 2 tubes but it will make them good with a 6 cent price.
I don't understand friedcat's thoughts on this. He would sell more of them with a properly programmed controller. I may have went for 5 of them maybe 10 of them.
These would be an easy sell on ebay at 650 usd. 10 for 7.9 btc = about 380 usd each. I could sell 7 for 600 after fees and pay off the 10 leaving me 3 for free.
