Why is this so much higher than your other group buys? $130 for 40GHS plus some kind of group ownership of the hardware is much more appealing than this.
That deal won't start hashing until the end of February at the earliest, so that's a month earlier in terms of difficulty increase. On that one the hosting costs are taken out of the mining, in this case they are added to the cost (I think, unless I'm misreading something). Also with ownership you have risk of down time, but with cloud hashing presumably you don't (again I'm not positive).
I'm interested in what DZ has to say on this.
