Surfboard Help!!!

Alright, so I'm 15, 6'1 and weigh about 175 lbs. I live in Sarasota, Florida. So the waves aren't usally very big, but seem to be getting bigger in the Venice (the jettys). So I really want to get into surfing because I love the beach, and the water, what size board would be good for me? And whats shape (links possibly). I wouldn't want to spend that much money either.. Thanks alot!
