I do have a SW Zeiss. Admittedly it is not my most used camera, but I do put a fair bit of film through it. Usually with a scale focussing lens like the 25 Snap Shot Skopar or my Nikon 21f4.0 F lens with a F-L adapter. I also use it for my favourite truly vintge lens. A pre-war Zeiss Tessar 28mm f8.0 on an orion style adapter. Great lens, tiny package and if you stop it down to f32 it looks like a pinhole! Has all the hallmarks of prewar widenagles too. Lots of edge fall off, flare and no coating gives it a rather "mellow" contrast.
I have been using it with the 18f4 Biogon too. Only problem I have with that, apart from its size, is that I tend to use the 18 in close focus a lot and the lack of rangefinder coupling comes into play. I have no problem judging distances 1.5 meters and on, but woefully screw up in the 0.5-1 meter range!
If you are going to be using LTM mount lenses, I would suggest the Bessa L as you have the option of using adapters for use on other M type bodies, but with straight M mounts the Bessa T and the SW are the only choices.The AE feature on the SW is nice, but you have to watch for lens coverage as the wider lenses take in a lot of sky outside and usually pick up peripheral light sources indoors and skew the meter reading a bit.
