Do your research. I just talked to an owner of a two-year old 250 yesterday...he has had a lot of problems with it. Not all of the problems were covered by the warranty, either. These problems cost a couple of thousand, and that's after the dealer absorbed some of the labor costs. I know that this guy is easy on his equipment, which worried me.
I used to think that the Deere would be my first choice for a skid steer to replace my LX665 New Holland. Now, I'm not so sure.
The Series II machines were supposed to have a number of changes. The specifics of the changes, I don't know.
