Richard, I'm in agreement with Flavio on this topic. I have a cabinet full of old cameras and lenses, all of which work and have functioning meters. Including Spotmatics and a beautiful XD-11. And a first generation Nikon F with the non-TTL finder that has the big port hole in the front. It works and it's accurate, to boot. Along with that F, I have two F2s, an F3, and an F4. I love 'em all. And Canon FD! That's what I cut my teeth on, so I'm particularly fond of my FD collection. Two old F-1s (meters are dead-on accurate), a New F-1 with AE Finder, a couple of FTbs, a few EFs, an A-1, an AE-1 Program, a T70 and a T90. All are clean examples (well, except for one FTb that's been around the block a few times, but it still works fine!) and all function as they should. I have about a dozen FD lenses in both mounting styles, and not a one of them is in need of lube replacement. And as for cameras that took the old 1.35v PX625, I use 675 hearing aid batteries. They're cheap, have a voltage that's close enough (1.4v), and the same discharge profile. I'm a huge fan of the cameras built in the '70s and I see most of them as having life spans that are indefinite as long as they're treated well.
I can understand why you would recommend something more recent to a newcomer, and I think it makes a certain amount of sense. But I also think that many more recent examples won't have the life expectancy of the old, tried and proven gear. For example, I own a Nikon N80 -- and I really like it a lot. It's quiet, feature laden, has multiple AF points and a good selection of metering patterns. But it's already around 10 years old or more and I question whether it will still be a functioning camera in another 10 years, where I know my F2s and my old Canon F-1s will be. Or my Pentax KX, or Nikkormat FT3, or Canon FTb . . . So, I guess I'd do my recommending on a more case-by-case basis. If I thought the party was up to dealing with the old stuff, I'd recommend it.
