If your not in a big hurry hold out and pick up a xp model.  If you want a used one, I'm sure there will be a few around this fall with the 2010 models coming out around august.  My brother just bought a new 2009 550xp camo for around $6200.  You will like the new models, easier steering (even without the power steering option), more power and an even better ride than before.  I'm partial to my 06 800, 1200 HARD mudding miles and no problems.
