I have had for several years now and love the way it cooks.  I would recommend watching both the Kamado Joe You Tube videos along with the Smoking Dad BBQ videos to get a great learning curve on use and accessories.  If I was purchasing today I would go with the Classic III but other than that the Classic II has been all I have needed for the family cooks I do.  If you want more space the Big Joe would be the answer but the accessories cost about 50% more for the larger size.
