I have had my eye on the Fargo, as well, if I ever go the 29'er route.
Then RFC, think about the gruppos between the stock Fargo 2 and 3.
I happen to like the Deore gruppo with bar ends, but if I could find a used Deore XT gruppo, some Avid 7s or better, and a decent 29'er wheelset, I'd just buy the frameset.
Pretty simple to figure out the right direction if I can get my hands on a large Fargo frameset.
This would be a better bike in the snow, on singletrack trails, and fire roads.
The need for a Pugsley then, would be reduced.
....and with slicks and racks, a lot, lot more.
