[...] so IMHO it's not worth the electricity to mine at this point.
...that's why I turned of my dual HD5850 Bitcoin miner in June 2011 - it was simply not worth investing the electricity for the lousy 0.8 BTC (per day) I could earn by pooled mining these days...
This time I'm going to make other mistakes

When cost to mine>cost to buy, you're better off using cash to purchase it on the market.
It's still far too difficult to get cash into the ecosystem. At least for Americans.
I can use mtgoz, but that incurs wire transfer fees
I can use virwox, but you get hit with many 2.5% commissions (I think there a fee to make initial deposit, another to sell dollars and buy lindens, another to sell lindens and buy BTC, and yet another to withdraw those BTC.
I can use campbx, but I have to wait 30 days before dwolla will let them let me withdraw those btcs.
Or I can use local bitcoins. But everyone there seems to charge 10-20% more than the mtgox price.
That's why people mine even when mining costs more than just buying the coins.
