I had an FG a few years ago-very capable little body. I probably put 75 rolls thru it with no problems. The good-TTL flash with standard ISO flash shoe, accepts motor drive, right hand grip, aperture priority, program exposure mode(but I never used program), the LED's next to the shutter speeds light up in the viewfinder-easier to see in low light than match needles. The bad-top shutter speed is 1/1000 and flash sync tops out at 1/60.
I also had a few 50 1.8 Series E lenses over the years. It seems many of the Series E lenses would get slack in the focus helicoid with heavy use. It would be best to find one that looks great cosmetically-that's a sign that it didn't get used much.
