Welcome aboard!
I used to work for a JCB dealer. We only sold one before the owner went through a divorce and the company dissolved. They are nice machines, related to Volvo Heavy Equipment... I can't remember who made them, JCB or Volvo. But yea, single side arm, easy in/out cabs, etc.
The parts software was pretty good, too, for the newer stuff. Never had to look up old stuff. I was in Parts, and we serviced lots of stuff including cars, so didn't spend much time in JCB.
