tell us more about your situation what you are doing with your bucket and forks, what is your budget, do you need another tractor far anything?.  Adding a older tractor for the auger would be the cheapest but something else might fit your operational goals better.  Each tool has its own place as you know with the tractor loader you need some space to move around but have good reach for height and good lift capacity and you can use the tractor for other things.  The skid loader works good in tight places and has a huge assortment of attachments for pulling trees, mowing brush, drilling holes, picking rock, spearing bales, backhoe, trencher, grinding concrete jack hammer.  The telehandler I will have to leave to someone else as to what they do best I have not run one.
