I have the A1 and love it - when the mirror develops the squeek, it needs oiling. Batteries are still readily available and are mainstream (at least I havent had a problem finding them). The final development of the A series was the T90 which was their last before the EOS. I recommend the T90 for the spot meter, faster top shutter speed and built in motor. Then again I still love the A1 and the AV1 is similar. The FD lenses are so cheap its a joke. The 85 1.2 was sold recently for less than $500 recently. The 50 1.4 is usually around $50.
