GR2100 reliability?

So a local implement dealer has a GR2100 with about 250 hours on it (Gas v-twin) it's really clean and appears well cared for. I've read though that the tranny, pto clutch, and glide-steer system can be problematic on these. Anybody have any input, especially the service dept. types?
Haven't had a chance to run it.

Quick update on this question. So... a nearby Kubota dealer basically implied don't take it if they offer to give it to you! "We have 3 of them sitting in the lot at our other store because customers refuse to put another dime in them". Got to appreciate their honesty!

Yeah, but if you're faced with the prospect of dumping a couple grand at a dealer into a "mower" repeatedly for mechanical problem that is likely to recur then there is a point where cut quality and other niceties don't matter so much.
The glide steer is an interesting concept, basically replace the differential with a set of clutches that disengage one axel or the other when turning. Someone apparently didn't do their homework though when assessing the axel loads on the first version transmission. If I knew enough about the tranny case and I thought I could machine it to accept an upgraded bearing I might be willing to take a chance on one. But it's a lot of work for an experiment unless you get the tractor for practically nothing.
