I would be in for an investment pending the setup and hw pricing. Was looking at buy an SP50 for my farm, but would love to get lower than .075 electricity like I have now.
The thing with the CO-OP I think if we go out and find cheap electricity for it we could easily beat that. I would hope .03-.04 would be my goal range for the mining CO-OP to be able to compete with the "big guys".
Finding the right place for electricity and setting that up would be a big part of the initial setup period.
