Head over to mtbr.com forums and then the Fatbike sub-forum. I'm looking for a fatbike myself and have been spending lots of time on that forum for the past 4 months. Lots of discussions on all the various fatbikes, Moonleander & Pugs included. Currently I'm hooked on the 907 fatbikes, just waiting for them to be back in stock in my size.
