It will depend on how much I like the tournament and if it is worth it, when the tournaments are big, with big prizes to be distributed I always re-buy, I can do it up to 2 times, but I don't go crazy re-buying every time, I always have a spending limit in each tournament, I think it is something I have learned over time, because sometimes you think about the re-buy when you just start playing, you don't concentrate very well, so I always re-buy twice, whatever happens in the tournament, I think it should be a habit for all players.
