What kind, and size wake board should i get?

i just turned 14 years old and I'm 5'4 and about 112 pounds. i have always used my cousins wake board but it is much larger than i need. with his board i could never really get much air... around a foot or two at most. I'm average at wake boarding, i cant do anything special but I'm not bad. what brand and size wake board should i get? I'd also like the the price to be not much more than $200 if possible
