Finding the right kind of tournament can be like finding a new suit. You want to find one that fits your style of play and bankroll the best. The three main things you want to look at first would be the buy in cost, the amount of players, and if there are re-buys or not. I myself try to avoid tournaments that offer re-buys, for some reason I just don't like them. Then again some other players love being able to re-buy in a tournament again.
