If you don't use it much and don't need a big machine, the case 420 is a really affordable machine. About 6000 hours on a 75XT and it hasn't needed much and it is used for concrete all summer which is not easy on them. I personally would go for a smaller newer machine to get lower hours. As far as how many hours to stay away from it really depends what the machine was doing, usually when your looking at it you can tell. But anything with 5000 hours or over I probably wouldn't buy. But then again it depends if your able to do your own work. They can be expensive if you take it in for any work.
I am personally all for Case, you cannot beat the Cummins motor, if they don't see 10,000+ hours without any work it's very rare.
