Question for those more exposed to these than I

Of the varied models I am looking to buy a decent HOPEFULLY tracked machine for our farm. Would be in a age range of ten-fifteen years, hours are not a deal breaker but I would expect to be using this for Fence work, land maintenance(grade and cleanup), other duties that come up with as pop up with associated attachments. Of the machines out there which is most versatile for least expense and will not drive me insane electronically?
