Heinen's moves a ton of bikes, so they have amazing prices, especially on closeouts. Dave got his Husky from there new last year.
6 of one, half-dozen of the other. The KTM's LC4 motor is damn-near bulletproof, as it's been in production for quite a while. Good accessories available, especially from KTM directly. Easy maintenance, including valve jobs (checked mine, haven't had to adjust them yet, after 3 seasons of riding). I can't speak for the Husky maintenance, but I'm sure if you wait, you'll get plenty of answers.
Looks? Well, the black Husky gets my vote for pure SuperMoto sex, even though I own an SMC.
I have heard of more overall problems with the Husky versus the KTM, but the Husky is at the beginning of its product life, the KTM is in its mid-life stage.
