Thanks error,

I thought so too (that I'd been lucky). I wonder what the odds are of three blocks in a month @ 'only' 2100Mhash/sec. I must say that I don't like the variance, however 150 BTC is *substantially* higher than I've earnt via pooled mining and if I find another block in the next couple of weeks I think I'll go crazy.

As for Slush's, my accepted/rejected block ratio is 2.39% rejected/stale; does that seem about right?

Thanks for your advice.
