Haven't seen the 3450, but I have a 3650. Put over 1000 miles on it this summer and fall. We live next to hundreds of miles of ATV trails in Northern Maine. My wife and I love it, especially now that we had the command lever fix done.
I have the bucket, snowblower, and lawn mower for it. It hasn't snowed much yet so only ran the blower about 10 minutes. The mower got lots of use as I mow about 15-20 acres at an old farm dad has. The bucket was used to haul heavy stuff around the house and I used it some to fix some pot holes on the trails and removing rocks frame the farm.
It's nice having A/C in the summer and heat in the winter.
I have some photos in the photo gallery button at the top of the page.
