I think the mulching head possibility may help rule out a lot of them. I understand that you need not only high flow, but good lift capacity. I bought the Bobcat T770 new 2 years ago. If I get to the property once a week, that's a good day. And we do not crank it during deer season It's now due for the 500 hour service if that tells you anything about how much I love it. My buddy literally does nothing anymore outside of bobcat work. When I was researching, it seemed like they all had pluses and minuses, but because a dealer is 15 minutes from my house, and they have numerous attachment I can rent, I went with them. The other feature I like is that the engine will bog down if you put too much load on it. This lets you stop and back off, keeping you from blowing the engine. My one mistake was getting a dozer blade simply because we don't use it. My buddy can grade with the bucket great. As far as used, I can't say, but I would think that any of them would be good IF they were maintained.
