Just realized after typing this how old the thread is.

Sometimes it's cheaper to buy the BTC, rather than the mining equipment, BTC price 4th July 2011 was just $12.80!!!

When we were mining on GPUs it was easy to make a profit but with ASIC it took me nearly a year to reach ROI, and you need to ask yourself, "is it worth the hassle of keeping it all running?"
I made about 10% on my ASIC investment so I'd have to say playing the rise and fall in BTC price is way easier than mining, these days, we just need the Fed to announce QE4 to see BTC rise again!
