I'll keep my eye out. I just find it all interesting, even at small scale, you learn a lot. Two years in a hobby you're interested in can bring a lot of lessons and insights. I like the larger scale perspectives on it all too.
I've only been doing the heater thing with a Canaan since December and it's out getting out of season now. Other than that it's just bitaxes hashing at my work desk. It is, however, addicting.
