I saw this on another site, by a respected player.  Note these are the max you should have.

multi : i believe its 200 or 300.
sngs: 50
limit: 1000-2000bb's.
nl: 30 max buy-ins. 3000bb's

I would say for multi's 100x is the bare mininum, but 200x to 300x is much better.
sng's I would not have less that 30x at your disposal.
Limit I really how no clue I would have to say 1000bb though, that would garunteee profitablility for me at least
NL I have always thought about 10x to 15x buyin for a min, and 1000 to 1500 bb's

These may seem a little crazy and I doubt that many people are able to be this disciplined.  I will say though that if you are probably bankroll for the limit you are playing bad beats don't seem to effect you and in turn you play better after a bad beat.  I mean if I have 4k in my account and I am playing 2/4 limit and get 2 outtered on the river adn lose 100 that is not really a big deal, but if I have 500 in my account and I lose that say pot their goes 1/5 of your total money for poker, which in turn will put you on tilt.

You may also think the mtt bankroll is huge I mean for $5 tourney you are talking 500 to 1500, which I think is basically dead on, I think we the huge mtt fields and beats you take you need even more money to substain the variance.
