Need help buying a snowboard

Leaving for Vermont next Tuesday and ideally I'd like to pick out my board online so I need to do it ASAP (my two local shops completely suck) My budget is $250 for a board and I wear size 13 boots so Ill need a wide. Its been 2 years since my last purchase (got an enduro and it delaminated after 2 years of scant use). Anyone have any suggestions? Also does anyone have any opinions on the the brands M3 or LTD?
