I've got a NH LS170 and can handle pallets up to 2,500 lbs, but I am right at my limit there and wouldn't want to drive with the load very high off the ground.  If you aren't trying to get into tight places, a 180 or 190 might suit your needs better.  I would never own anything other then a NH skid steer because of the Super Boom and mine will start even at -10 degrees without plugging in.  It's inside, but uninsulated building.

For sloppy conditions, I have a set of Tracks Plus tracks.  Better floation and smoother riding then Grouser's.  Cost a little less too.

I've got a post hole auger for it, and hydraulics are more then adaquate.  I've got a soft cab enclosure that I use in the winter.  On a cold day, it sure helps.  No heater.
