You have specified a single lens camera that is inexpensive. The advice to get A Kodak Medallist is certainly very good advice for a camera that will not be overly expensive. The optics on the Medallist are first rate. The cameras will be quite old because I believe that they have not been made for over 50 years. They are a reliable camera but getting one repaired could be a problem as far as parts are concerned. Many younger photographers do not know what a world leader Kodak was at one time as far as optics are concerned with products as good as could be found any place in the would.
You might also have a look at the various folding cameras that were made. Fuji made a number of good rangefinder cameras that are much more modern vintage than the Medallist and that may be available at a good price. Good luck in making a good choice.
