Well depending on what you weigh Line Lizzies might be a good option for park and trees. Depends alot on whether you are more in to jumps/jibs, also on whether you would want a wide/short snowboard style ski. Available cheaply on evo outlet.
Other options under 400:
Chronic Cryptonite (Evo Outlet) but longest is 173 so maybe too short.
Volkl Ledge (Backcountry outlet)
Line Step Up/Abangs (Backcountry Outlet)
Line Anthem if you can find them
Whats your budget? What size are you looking for?
there's a certain point where it neither looks good nor functions properly...that's when you know you look steezy - no_steeze
