Should I keep my racket or buy a new one?

I currently have the prince ozone 4 and its head size is a little too big for me. The main problem is that I lose a lot of control because of the oversize head. Are there any rackets out there that have a small head and is light weighted. I want to have a really good racket so anything that is under $200 is fine. (I am 15 btw). Thanks for the suggestions!
