Why don;t you get a used Zeiss Contaflex/Contina/Contessa or a Voigtlander Vito/Vitessa as a starter VF camera. They don;t cost more than $100 and except for the lightmeter are usually fully operational.
If you are lucky you may even be able to buy a Contax II or III for not too much money. Or one of the newer Contax G1/G2.

Also a russian copy of a Leica/Contax (FED or Zorki) can be a good starting point for you to get a feel of how a Rangefinder feels/holds/shoots, etc.

None of these cameras (excpet for the conatx) will be as high quality as a Leica but they will igve you an idea of how the RF feels
