Facing the same problem - bought a mint boxed unused 1982 Nikon FE2 (posted pictures on the Classic thread a few weeks ago) and it looks so perfect I chickened out of taking it on a "spin" last weekend.

For that reason I'd never buy a highly restored classic car!

Talking of low frequency organs - I remember an old LP from Abba where there was a track called "old friends do" or something like that with the most shattering organ track that I have ever heard. Everything in the room used to shake. It sounded like a real organ, not an electronic one, so I wonder where they recorded it?
