I've owned the following:
Rollei 35 - Original Tessar model, black, made in Germany.
Rollei 35 - Original Tessar model, silver, made in Singapore.
Rollei 35 S - Sonnar, black, made in Singapore.
There is no difference in fit and finish or image quality between the Germany and Singapore cameras. Also, the Tessar and Sonnar lenses are both excellent.
The Camera Hunter has accessories for these cameras. You will probably need a lightproof pouch of some kind since the meter stays on all the time. The original Rollei pouch is nice, but I prefer my Lowepro, a small soft case with room for an extra roll of film, a hood, and a couple of filters.
I like the models with the meter on the top. It's convenient to look down on the camera and see all of the variables - meter, shutter speed, focus, and aperture. It also may be a bit more stealthy than those with the meter in the viewfinder. My recommendations would be the Rollei 35 or 35 T (which are identical with the Tessar lens) or the Rollei 35 S (Sonnar lens).
