Should be pretty easy job for a good tech. You may want to have it checked out to be sure the casing wasn't damaged at all. Living/working close to NYC I'm spoiled by having Josh Landress very nearby. I had a hole in the 2nd valve slide on my lightweight Bach Strad and Josh was able to replace it while I waited (and chatted with one of the jazz professors from Julliard who was just hanging out!).
