Low luck is really annoying, I got my first S3 last week dramatically increasing my hashrate from 12Gh/s to 450Gh/s... Still waiting to get a payout. 

My miner setup is minimal. A Jalapeno, a few Block Eruptors (not in use until I get a new USB hub), and I just received a second hand Antminer S3 yesterday which is powering through computations nicely.

My small mining effort is because I enjoy Bitcoins as a concept and want to be part of something that is different and I find interesting. I don't mine to make a profit but regaining some capital is nice. Even though electricity costs are technically higher than income from a Jalapeno and even questionable for an S3, I want to be part of the BTC community.

Now it's cold in my office I wouldn't mind some more miners, might get a few bits by running some miners instead of heaters... BRRR!
