Canon AT-1, FTb, AE-3, TX, F-1, A-1, FT will all fit that lens and provide manual controls. There are certainly more, but that's what I could think of off the top of my head. None of them are plastic. I think if you want a lightweight plastic body to go with Canon FD lenses, your options are very limited. Possibly some of the T-series? I have no firsthand experience with those.
For wide angles, an FD 28mm f/2.8 should be pretty easy to find and affordable; I'd check KEH. I prefer my Kiron 24mm f/2, but that's harder to find and possibly more expensive.
