fwiw I disagree with buying in max at all times. at 1/2 cent on stars I buyin at $3 which is 150bb (enuff imo) and is more than 90% of everyone else. It may be just something to keep me within a comfort zone (loss limiter within one hand) because I am still comfortable if I get my stack up there.
But I think if I was just starting out again I would suggest $3 is enough to buyin with at that level.
