Solo miner, running 440 mh/s, ran solo for a while, realized I would basically never find a block, switch to pool mining. That is where it's at. Especially with difficulty increases and the increase in hashing power it's better to join a pool. I'm part of Slush's pool, http://mining.bitcoin.cz
and have had really good luck in there so far. Have not found any blocks, but have made some bit coins, and at a rate greater than what it claims I should find a block myself.
