You should look at the Rome Crail, or if you're really looking to go with a Burton, the Bullet would be a good first board. Neither of these boards will break the bank.
However, if you don't have boots yet you should start looking at a getting a good pair. You can buy a low-end board for progressing your first year or two and buy a new one down the road. You'll want good boots from day 1.
i would say burton bullet or deuce.
depends on what you search in your board
