I bent mine on the Fourth of July last year. I was able to finish the trip to my brother's place for an extended weekend, although i could tell the bent rim and damaged tire wasn't going to get me home. Ended up buying a new rim and tire to finish the trip.
I've not used it yet, but it looks better than it did before I bent it! The big downside for me is that they charged my credit card when I dropped it off (only about 15 minutes from me). When it came time to pay the CC bill, I didn't have it back yet (they originally told me two weeks - ended up being about five). That's when I started pushing to get it back - SWMBO didn't want to pay for something we hadn't received yet.
I found that a lot of the places that will repair aluminum car rims wouldn't touch motorcycle rims.
In case anyone wants to know - cost was about $225 - YMMV depending on the actual damage.
