In rebuy tournies, do you immediately rebuy at the start?

well, yeah...im mean, if you hit the flop huge and win the hand then you are gonna be over the 1500 in starting chips, and you cant rebuy. And if there were a bunch of people in the hand, with chips flying around, hell you might even more than double up. In that case, of course, win the hand, take the chips, save the rebuy, and go on to win the whole tourney.....hopefully
