My all time fave 35mm SLRs are these (no particular order)
Contax S2b (all mechanical, but with a build in center-weighted lightmeter and 1/4000s max shutter speed)
Minolta XD7 black edition (or XD, XD11 into other regions than EU) simply a time less classic
Nikon F100 (for all your autofocus AF-D lenses needs, feels & handles like a Nikon DSLR)
Nikon F6 (if i'd have the money for it....because it was the pinnacle of 35mm SLR development)
fave 35mm Rangefinder
Minolta CLE (a much better "Leica" CL, Minolta CL (remember, all these are being built by Minolta, Japan,
Leica had 73-76 the Joint venture with Minolta, after the CL sold itself much better than the ugly M5, Leica
rushed out of the cooperation and canceled the production - Minolta developed the CL further into the CLE,
which was being 22 years ahead of Leica, until the Leica M7 arrived into 2002...a Leica M series like the M2, M4
series is still much more expensive...and 99% of all Leica CL, Minolta CL have a broken, or only partially working
lightmeter - this is not the case with the CLE..but you pay easy 1K for a decent, mint copy)
honorable mention
35mm SLR
Pentax MX (this was my #1 35mm SLR back into 1987, great OVF, small & handy)
Pentax K1000 (a true classic, but does have issues over the decades, no-frills, basic SLR, Pentaprism could develop issues)
Nikon FM(2)/Nikon FE(2) (again, time less classic 35mm machines....i miss my black FM...)
Minolta X-700 (more plasticky, not the same build quality as the XD series, but even bigger, better & very bright OVF) "Acute Matte"
focusing screen, once can eyeball into every corner...which that tech also was being build into various Hasselblad medium format gear.
Budget option
Minolta X-300, X-300s, X-370s, and chinese clones, like Soligor, or Seagull for instance. (Access to the great Minolta MD series of lenses,
bright & huge focusing screen, X-300 does have the best build quality here)
Yashica FX-3 Super 2000 (a cheap mechanical 35mm SLR with access to the Contax Carl Zeiss lenses, build in Lightmeter, and 1/2000 Top Speed,
or the fine Yashica FR-I. (1/1000s shutter speed)
35mm Rangefinder
Yashica Electro 35 GT/GS (not the latest of the series, but 99% the same, with a great Color Yashinon Auto DX 45/1.7 lens) Beware of the "POD" issue.
