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

I personally hate rebuying, if I get busted well it gives me the option to stay in but I'd much rather just play good poker instead of taking huge gambles and putting alot of money into a tourney. I usually don't add on unless I feel I have a chance of winning it . No point puttin 10 or twenty more in and then getting busted out the next hand.
