Saw results of a run over wheel recently, the whole thing was a goner, crushed the flange on the hub as well as mashing the rim. I'd try a new XT hub (more engagement and lighter now) and same rim, with some Sapim Race spokes and build it myself, but that's me. A shop should be able to do a good deal on that or a similar wheel (maybe different spokes). Maybe ask Ventanarama (Larry - Mtn High Cyclery)? Or another builder who frequents the forums?
