New rider looking for a board, what should i get?

I've been riding a few times before but never really got to ride frequently. The summer before last my friend has a 135 liquid force and i loved how it felt but i haven't rode anything other then a really old p.o.s. Im about 5' 10" and only 125-130 lbs. I can ride pretty good but havent managed to start learning any tricks yet. Im hoping to get a board that i wont have to replace after i start getting better as i plan on riding alot this summer. Id really like something thats quite light weight but im trying to limit myself to $400 or so with binding. Any recommendation? Ive always liked liquid force but not for and real reason...
