First off, if you could give us some basic information that would really help us decide on which board would most likely be best for you.
3. Foot Size
4. Riding Style or Projected Riding Style (powder, mostly groomed runs, mostly park, or a combination?)
5. Experience (which you did sorta give us, is this your second season meaning 3rd trip or second season meaning 10th trip?)
Personally, I'd be that you could find a perfectly decent new board for an amazing price (sierra has some pretty crazy deals going on, as well as just random boards at other places at really low prices).
Binding wise, that will depend a lot on your riding style and what board you pick.
Alas, however, I am not too familiar with the Burton lineup, so I can't make any decent suggestion regarding the supermodel. Also, I'm not too sure you want to pick a beginner specific board. Most people grow out of "beginner" boards really quickly, you're probably looking more for an intermediate board.
