OK, here's my situation in full.
I purchased a few blades which run at ~10GH each, two BE cubes and a BFL55

one cube died. (so I guess that's not going to break even)

I set a floor on the price I was willing to sell my BTC at €450

under that price, and I just plough everything I mine back into cloud mining. I see this as the only way possible that my rig will break even eventually.
I now have 170GH at home (from 205GH) and 60GH on cloud. I'll keep building the cloud with the btc I mine at home and when BTC price breaks through that floor, i'll start selling it on exchanges again.

As of now, i've not broken even. but I will, eventually because the cloud hashing - although a premium at 0.0075btc / GH, has no long term electric costs.
