You seem pritty set on Lib Tech, any reason?
If I was you I'd save my money. Buy a decent second hand all round board, whatever you can pick up for cheap. A beginner wont be able to appreciate the added tech the best boards give you so it'll be a waste of money. Then when you progress and understand more what you're into (be it park/powder/piste etc) and what you want from a snowboard then you can make a educated decision.
