I am at 650mh and I have been wandering the same thing, can anyone enlighten on what hashrate you should switch to solo mining. I have read a few month old forums saying over 100 was ok and I found one more recent post about anything under 5gh is not worth it. Would like to know from the big guys a good number to start looking to solo mine
Upto 500mh, stick to any pool.
500mh to 2gh, use ethpool because they will pay you the full reward for uncles.
2ghz+ you can try solo mining, but most solo miners are 50+ systems.
