I've seen Contax 167MTs on sale in B&S every now and then. Nice big finder (a pleasant surprise when i come back from cropped sensor DSLRs. I'm not very fond of the ergonomics of this model though -- most Contaxes had the shutter speed dial on the left of the prism, the 167 had a slide switch on the right of the prism; the in-finder display (shutter speed and aperture) is above the screen -- I find the position awkward.
I prefer the finder displays of the earlier 159mm and the 137MA. Both had a row of LEDs on the right side for shutter speed. You might find the shutter speed dial position (left of the prism) awkward. Depends on how you like to shoot. The built-in motor drives on the 137 and 167 were impressive, not adding much depth or weight to the bodies. I used each of these 3 as my main camera at different times, and I like the 137 the best. The 159 was the first Contax with a 1/250s sync speed, and the shutter was rumoured to be somewhat delicate -- mine failed after ard 5 years of moderate-to-heavy use.
I have also used a FX-D (based on the Contax 139, predecessor of the 159). I prefer this over the FX-3 cause I shot in Aperture Priority mode most of the time. Have also seen the FX-3 on sale on B&S every now and then, but I don't really like to shoot in metered manual mode.
One 'advantage' the Yashica bodies have is the more conventional shutter speed dial on the right of the prism.
I remember trying out the Yashica FR (FR, FR I and FR II ) range in the shops -- never did buy one, but my fav of these 3 was the FR1 -- A & M modes, full exposure info in the finder.
I never used the later models (after the 167MT). I'd have to say that my fav of all these would be the Contax 137MA and Yashica FX-D. It's been a while, but I think the Contax had a brighter finder. The FX-D was lighter (no motor-drive) and a real bargain
