I still think it is worth it. depends on your strategy though.

I checked my pool address just now and I am expecting 1.9 ETH a month (went up by .09) and I pay $230 for unlimited electricity for my house. I know this number can fluctuate based off of difficulty.

I am not worried about the price per ETH at this moment because I am still making close to $800/month at todays prices. I am mostly mining for the coins at this point though. I am looking for a big jump on prices throughout the year and will sell at that time.
