The Voigtlander Bessa R2A is an awesome rangefinder. Their price is slowly creeping upward. Buy one or two now while they are still reasonable.
Be sure to put a bottom on it.
Or better yet, this bottom.
Aids the handling and solid feel considerably. Careful with the winder not to hit rewind pin on base of winder before roll is finished - otherwise film advance problems.
If you do buy, buy from Camera Quest Stephen Gandy. He offers good service, but he will NOT service if you don't buy from him. Camera quest also on Ebay.
