What size UTVs are you looking at? A new Honda Pioneer 520 starts at $10K. You'll probably want some options, so it goes up from there, but still fairly reasonable.
I use it to get work done in my woods. I went with this over an ATV because I wanted the bed: I haul a couple of chainsaws, fuel & bar oil, tool belt with wedges, axe, lifting tongs, peavey, basic chainsaw tools (for sharpening and minor adjustments/repairs), helmet, basic first aid/emergency kit, food & water. I haul a trailer for firewood, if that is what I'm working on. If I want to go for easier maneuverability, the trailer stays home.
I have no need to go 65 MPH (most of the time I'm under 15 MPH). I did not want to go big: the idea was to get something that was lighter on the land and could get into tighter spots and past choke points when cleaning up storm damage. When I have bigger jobs to do, I bring the tractor & logging winch and/or a forwarding trailer or dump trailer.
