Have an '01 MX 240 with 4,800 hours we bought in '03 with 800 hours.  We had to replace a couple of hydraulic lines the first two years but haven't touched any of them in almost 3,000 hours.  We just replaced the CAPS pump this spring and the electric lift pump last fall but really haven't had any other big repairs and only a few small ones, mostly replacing sensors and a couple switches in the cab.
