Do you have a price range? You can find last years models for some of these on the web still for cheaper, but i'm showing them as normal pricing.
400ish- Capita NAS, Salomon Time Machine, flow drifter. These are really really good boards for the money, even if you spend more you aren't getting much more from your board, spending much less you are missing a performance price point.
450-600 Rossignol One Magtek, K2 Turbodream, Arbor Coda, Burton Custom(flyingV of camber), Capita Black snowboard of death, Flow rush, salomon man's board or assassin. Lots of choices here I picked my favorites.
I'm guessing you are a medium to bigger sized sized dude, 170-200 lbs, 158-160cm will be a good size for you. I'm really liking the salomon boards at the moment.
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
