I use Bessa R2 myself. Tough little camera, a little bit loud though but very reliable and the CV lenses take good photos

If you want to buy, I recommend Dr. Joseph Yao from Hong Kong. He deals with grey market CV products and I got all my CV stuff from him. He could be contacted at
joseph@yao.com He has an impeccable reputation and a gentleman to deal with. Hope this is helpful.
