Russian Leica copies can be had cheaply (though I've used one, despite owning several). I have various 120 folders, enjoying using them all. None are rangefinders (relatively expensive on a folder) so all have to be focussed manually, mostly by distance guesstimation. The process of taking a picture is often slow and deliberate - the Zeiss Ikon 517/2 that I have been using until recently needed about 6 different steps to be taken before pressing the shutter. I have recently started using a Zeiss 6x9, yet to see the results, ditto a Voigtlander Perkeo II, both very nice to use.
