I had a 98' Banshee. Maintainance isnt really that bad, except when you buy parts for the Banshee in particular, remember you are buying parts for 2 cylinders instead of just one. The only additional maintainance to a 2 stroke rather than a 4 is rebuilding the top end.

I am thinking about buying one also, and probably will get a Raptor. The 4 stroke is a great all around fourwheeler, with plenty of ass on the bottom end. Although, nothing rev's like a 2 stroke.

I would get the Raptor myself, since I am brand loyal to Yamaha. I have seen/heard great things about the Kaw's new contendor in the performance ATV Market. I witnessed that stock Kaw absolutely blow away a modded 400EX, modded Warrior, and hold its own with a Raptor (jetted and a pipe).
