I'd agree with atcoequip, JLG 's are really bulletproof, tough machines. Very simple to work on also. How big of a machine are you looking for? The new jlg/cat 10k and 12k machines are really nice, but they are much larger and heavier than what you have now (I think- I don't know how big bobcat telehandlers are). It does make a difference in getting in tight quarters, and makes a big difference in hauling. I ran a older terex (10k cap?) a while back on the same site as a 8k jlg and the size was a big difference. The 8k jlg was way more nimble and easier to use, it was just a little shorter in reach and capacity, but for 90% of the work you jumped on the jlg before the terex (no one liked that terex). It was on a 3 story building and the jlg wouldn't quite reach the top, but for everything else it got used first. Brick layers love lulls with their travelling carriage, its nice for getting in and out of blocks set up high. A lot of telehandlers have aux hydraulics, I also see where some have remotes for a man platform. You set up the machine, then can step in the man platform and can run the boom up and down. I really also like the machines that have one control for all the functions (joystick and buttons), instead of this three different stick nonsense. I've run too many with hand, mid arm nudges, and elbows, or hooking you're left arm in the wheel and reaching across. Outriggers are a mixed blessing, they really help in stability and give you much more capacity when reaching way out. When reaching out on rubber, you can feel the machine getting light, with the outriggers set, you have no idea until you are really in trouble. I like to put the outriggers most of the way down (1-2" off the ground)on a far reach, that way if it starts to tip, the riggers will catch you, and you know you're most of the way to capacity. All in all I'd go for around a 8-9k capacity, with you're aux hyd. and only buy a bigger one if you have to have that extra capacity. The frame/ wheelbase on the 6k lifts are usually the same as the 8k ones, so the 8k is free extra capacity. Avoid anything with a low mounted boom (actually I think bobcats are?) I detest their visibility. With any load picked up you can't see anything to the right, until you get the boom way up. Hope this helps.
Even still, they do make a good telehandler. Just stay away from the DH model Gehl, I'm not a fan of them.
