F4S was my favorite and still is but I no longer have one. FM2N is a super little camera, no longer have one. Nikkormat EL is actually pretty neat camera, have one and it does a great job. Nikon EM is surprisingly fun to use. Light weight, some restrictions but with workarounds by adjusting iso etc.
F3HP is another great to use workhorse. Mine is broken but not for long.
