I live in the US and have purchased two Voigtlander Bessa cameras from Stephen Gandy at Cameraquest. One is the earlier R model which accepts the Leica Thread Mount (LTM) lenses. This model is often described as being more plasticky and less reliable than the cameras that followed. I have used this one quite a bit and though it has received the normal abuse expected from normal use, I have had no problems with mine to this point. However, if it does, I have quick access to service through Cameraquest.
My 2nd one is the R2C, which uses the early Contax Mount common to the Contax II, III, IIa and IIIa cameras. I love this camera because I can use all my Contax lenses in their native mounts. This one does feel a bit sturdier than the R model and, again, I have not had problems with this one either.
There are good things and bad things about these cameras. On the plus side, they are much less expensive than a Leica, they have very nice viewfinders which make them easy to use and they come with in-camera metering. On the minus side, the rangefinder does not have as wide of a baselength as the Leica cameras. This means that they are best used with shorter lenses. In fact, they come with built-in brightline masks that only go to 85mm. Another minus will be their build quality. While they are certainly good cameras and fairly robust, they will not equal the build quality you receive from a Leica.
Overall I think that they are an excellent value. For the price you will get a very, very nice rangefinder camera that is capable of using all the lenses you can use with a Leica, though you may want to avoid the longer focal lengths.
