... generally I would run with the idea of budget for 3 times the buy-in ... money to be made at this price.
I played in an amusing re-buy qualifier yesterday for the $11k g"tee on Betfair ...
Betfair managed to find a whole 5 runners for their $15 re-buy for two $109 g"teed seats ... so it should have been a value sit and wait for the freezeout ...
First two hands I have KK ... busted both times ... so three buy-ins by hand three ... the cards kept coming and prescedent set we never made it to the freezeout period with me qualifying for $46.50 ... (32nd from 82 in the actual event)
Generally for more sensibly run ans structrued re-buys playing decent starting hands can create a decent stack at reasonable cost.
If there are people trying to pump the pot ... rub your hands ... wait for the cards and enjoy.
