M5.
First Leica with TTL, 25 years before they managed to do it again. Last of the hand built Leicas. A Lwica masterpiece that was poorly marketed and arrived at a time when pros had migrated to Nikon and CNon SLRs.
While the ignorance about the M5 puzzles me, I'm happy that it keeps prices low. You can pick up a beauty for $1000.
My suggestion would be an SLR with a 50mm macro and a 105mm f2.5/2.8. The MP won't do close ups or macro easily and is not great with a telephoto. I would add a plain prism Nikon F.
