I sadly had no room for anything other than a bench top mill, but I have to say I've been pretty happy with my g0762. I'm envious of living anywhere close to Grizzly!
The only complaint I've had with my mill are minor:
The gib lock handles were made from uselessly soft pot metal of some sort, and the handles were too long (sometimes interfering with the dial handles or table). I ended up just removing the handles and leaving the bare hex head screws. I hung a t-handled nut driver nearby.
The drawbar was a little too loose in the spindle and would rattle around. I just made a little bushing at the top of the spindle which helped tremendously.
The mechanical power switch rotating plastic knob eventually fell out, but I leave that on all the time anyway, and just use the electronic power controls and EPO button.
It's slightly out of tram in the nod direction (about 0.0015") but I doubt I could tram such a heavy square column head any better with shims (and dread the thought of trying).
Overall it's been a great machine.
