So here is the story. I've been mining since mid June and by July I had 3GHash/s. Since I've been mining on deepbit I have found 3 blocks; two in the last difficulty and 1 in the current difficulty. Also I've only mined about 67 bitcoins in the pools. So I'm missing out on many many bitcoins...
So does anyone have a compelling argument for either solo mining or pooled mining??
If you have to use some percentage of the the profits to cover costs (like any real business at scale) pool mining is the way to go.
