I once dropped my FE-2 with MD-12 and 28mm attached to it, onto a concrete floor. That thing hit, HARD! It just dented the top corner by the film advance lever. I could recock the shutter, but the film wouldn't advance. My camera repair guy just removed the top cover, pounded out the small dent, and it is as good as new.

I still haven't replaced the divet in the concrete floor....
