In a under 8000 lb CTL you could look at a deere ct315,a very simple machine and should be petty tough for a rental machine.They also make wheeled ones the same size.I would keep what ever brand machines you get bare bones so there is less stuff to break,and easier to learn.A deere 323d CTL is a great machine to but is 8550 lbs.I also think I would stay with a radial lift type machine.
