Love my FM3A - it goes everywhere with me. I think I shoot twice as much through it as my F100.
I have added the E screen and the following AIS lenses: 35/2, 50/1.8, 105/2.5, 180/2.8 and 35-70/3.5. Great kit and combined it cost less than I sold my M6-TTL for. The 35/2 AIS is a phenomenal lens and stays attached to the body 95% of the time.
Best of luck,
