We've used the shop that's next to Motel 6 in Wendover -- more than a few times. I don't remember the names of the guys that run it, but - while they look kinda like you'll wait for everyone that lives in their block at home to get work done before it's your turn -- they haven't taken more than a couple of hours at the longest. I don't know if the spin balance or bubble balance or suspend the wheel between a couple of tacos, but last SW they swapped a front tire for us (when we had developed a chunking problem on a front, believe it or else!) during our long lunch hour, and that afternoon both Jason McVicar and I rode the bike over 200 without any balance issues. Take that for what it's worth. I think we paid 'em $15. And since there's an ice cream and taco shop in the same building -- you can eat while you wait.
