WTB Fatbike (Pugsley/Moonlander/Mukluk)

I was going to get a 9er to add to the stable of cross/road/track/commuting, but was thinking I might enjoy a fatbike more (open up the possibility of offroad touring, more fun offroading, etc).

1) Does any one have a Pugsley/Moonlander/Mukluk for sale for less than retail?

2) Thoughts? I know bikes and their uses are very personal, but just curious.

Thanks!
