i would say really dont buy a used board.... chances are it has been thrashed to hell and will break in about 3 days of hard riding, your not going to be able to find a decent board for 200 dollars in your size though, i would say look around this time of year for mega deals, before you buy a board buy your boots and bindings so you can check to see if you will get toe drag on the board.
to your question i would say a rome or capita, i ride a sapient and love it but i dont know to much about their other boards
