boards and bindings are fine.
I would just spend a little extra on good boots.
uncomfortable, improper fit, or just plain worn out boots can ruin snowboarding for you.
go to the mountain shop and try all the boots on and get the most comfortable ones in your price range, you will want to spend at least 150 bucks but definitely not more than 200. It will be totally worth it. good brands are burton, thirtytwo, K2, ride, DC, nike.
