Unfortunately, I have an Atari 800XL and and 600XL both with dead mylar keyboards. I'd like to fix at least one of them and wondered if someone had one (or more) of these computers I could use for parts that might have a good or repairable keyboard?

I'd rather have the mechanical (keyswitch) keyboards, even though I know I could buy the mylars from Best- I'd rather not if there are better keyboards out there.
