There are no "real" FD to EOS Adapters. Dont let urself get fooled. FD lenses are so long they will hit the mirror (on a FF DSLR). On APS-C they wont hit the mirror but its still not as easy as M42 to EOS.
What u want is a real conversion kit which replaces the FD mount with an EOS mount but they are not cheap.

Just pick ur favorite focal length and aperture, basically there werent many bad lenses since photography wasnt so mainstream like today .
its way cheaper to just get M42 lenses which really only need some 10$ adapter to work on all EOS cameras. Or just get some old m42 bodies (pentax spotmatic is quite good and widely available).
Most of my lenses are m42 tbh since theyre just so cheap. No prob with manual focussing it just takes some time to get used to it.
