I have a 101, very rough condition but works, a X700 that needs the shutter serviced, hangs up in hot weather, and a 7000, a couple of 9000s with motor drives, 600si, 800si, 900si, a 7 and 9. Of the AF bodies I seem to grab the 800si more than the others. The 600si or cCassic is really easy to use, dials as opposed to menu driven, both 700 and 900 are menu driven, uses those stupid cards for advanced features like multiple exposure or bracketing, heavy cameras with fast and accurate focusing. The 7 is the most advanced and will work with new Sony lens, the 9 came before the 7 had to factory modified to work SSM lens. Stainless steel construction, there was a Titiumum version as well which are somewhat collectable. The 9 has one, only one flaw a dim viewfinder readout, hard to see in dim light. As I live in the desert Southwest, I use the A600 or 800 more often. I have never taken the 7. The 9000 was the first pro level AF camera, and is itself odd. The Minolta pro level XK came in a nonmotorized version and an integrated motor drive version. Pros were unhappy at the thought of buying 2 bodies as with Nikon, Canon, and Pentax you could take the drive off when not needed for a lighter and quitter body. Well the 9000 is the only pro level AF body with an optional drive or winder. The Nikon F4 and Canon EOS 1 of course has integrated motor drives. The drive for the 9000 uses 12 AA batteries, the camera body takes 2 and full flash set with all three flashes another 12 AA batteries.
