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!
