With that width requirement, there aren't too many different models that you will find. I would do a little research and find out who has the best parts and service department where you live (unless you plan on wrenching on that bitch yourself when it breaks down). For what you are wanting it for, I would look at that criteria and then buy the most cost effective unit you can find. If you aren't throwing a couple thousand yards of dirt a day with a hoe, you should be able to find one that fits your needs. I would suggest looking at purplewave, RitchieBros, and other auction sites to see if you can find a used one. It will probably be beat to crap, but will most likely work for digging a couple of feet deep in dirt.
