Believe me, anything over 150 is going to be hard as balls for you to control. If you REALLY want to go bigger you could try maybe a 148, but thats the absolute biggest I'd go. You're not going to find much in the performance category with that price range. How long have you been riding/what's your skill level? Park, race, or all-mountain?
Start looking at older models, or slightly used setups as those are going to give you a much better bang for the buck. Is this only for the board, or bindings also?
Pray for an early start to the season!
