I own both a 2000 series and a 3000 series. The 2000 series was purchased new and I bought the 3000 series as a well loved, low hour, used machine after it practically feel in my lap. Both have been very good to me, but there is no comparison in operating them. You've heard the old adage Cadillacs and Chevys I'm sure. You can't really go wrong in my humble opinion with either, but the 3165 looks to be the better deal if you can swing it, especially like Mike said if it has the diff lock. One more thing to remember is that with either machine you should be living with it for a long time. Factor in the price difference over a number of years and the gap doesn't seem quite so wide. Then again it's real easy to spend someone else's money!
