All of these cameras are quite good and will do what you want.
But if you really are interested in using one of the best then find a serviced Pentax LX and enjoy shooting a light, professional camera with a very, very accurate meter. It may turn out to be a tad high for your stated budget but you certainly won't mind once you have used one for awhile.
EDIT - Of course it was still being sold in 2000 so it may not quite be vintage enough for you.
Amen to your statements! The LX has perhaps the best metering system ever. It will meter night shots, in my experience, to 10 or 15 minutes. Others have had successful exposures of several HOURS. The meter measures light falling on the FILM during the exposure, so changing light is compensated for. For close up work several different viewfinders are available (if you can find them) and since the meter reads off the film there's no worry about light entering the viewfinder. Interchangeable screens, too.
TTL flash metered off the film. Works really well.
The LX uses readily available silver oxide cells. The cells control shutter speeds below 1/75; all above are usable without power.
A winder is fairly readily available, 2 fps, and power rewind. Woo hoo! Also a motor drive, bulk film back, etc, etc. A full system camera.
Any K mount lens will work properly with the LX. With an adapter 42mm mount lenses will also work, but in stop-down mode for metering. I'd suggest trying to find the genuine Pentax adapter, imitations have been known to give problems.....
Cost? I lucked into a clean user from KEH not long ago for well under $200. A little brassing, a little dust, but works perfectly.
Naturally the LX has its faults. Metering is center weighted, but I "grew up" with that. The most irritating omission is the lack of an exposure hold button in the automatic mode. What was Pentax thinking??
