You don't say what inexpensive is. I never pay more than 25 for an old camera - inexpensive is less than 15. Some [people are rich and will pay 100 or more for a camera. How much is your 'inexpensive'?

At my end of the scale, I would suggest a Franka Solida III which has an uncoupled rangefinder. Mine cost 12. My favourite folder is my Zeiss Ikon Nettar 515 (6 x 4.5 format on 120 film) - no rangefinder or light meter but excellent lens. I think I paid 10 for that one.

At a more expensive sort of inexpensive (100 to 150), I would suggest a Super Ikonta - coupled rangefinder, choice of lens and shutter. I am waiting to find one for 20!
