One thing to remember is that if you find some good used equipment at good prices, then you can probably still make it work. Just because the bushhog is 10' wide doesn't mean you have to cut a 10' path all the time (except for the first pass, of course). You can always make the first pass in a lower gear, then take 7' or 8' bites instead of 10' at a higher speed.
Good luck and take care.
