I'm new to CFM, just picked up my 1000 last week...ive ridden motorcycles and quads my entire life 20+ years.  I have to say CFM seems very legit.  I had been debating the 2 models for a year or so.  My decision came down to the standard equipment.  the 1000 comes with the skid plates, bead locks, cargo etc...these were all items i ultimately would have added, when you add all the upgrades you are way past the msrp difference, and you still have a smaller 800.  The 1000 is a beast.  Still "breaking it in" and haven't had the chance to really test it but, it is definitely worth every $
