Wouldn't just buying a folder like an Ansco Titan, Billy Record, etc. be a lot easier way to try out medium format? Not to knock your idea, but the only reason to use a Koni I can see is to try out different lenses (which I don't think you have) and different backs (which you don't seem to have) so as to do +/- development. I think there are a lot of coupled and even uncoupled rangefinders to be had for less than $100 or even $50. I suppose there are some people who can't come up with $100 or $50. If that is who you are trying to attract then is this sort of like a drug dealer offering the first one free? Just make sure you follow it up with, "You can't always get what you want, but you can always get what you need." :-)

Best,
