I beg to differ.

The OP never mentioned wanting a rangefinder camera that does up the price, and speaking from experience it's remarkably easy to estimate the distances and set the focussing manually on these old folders.
I'd forget ebay for something like this, best place to buy is car boot sales, flea markets, camera fairs, garage sales (rare in the UK), and some charity shops - but many sell their cameras etc on Ebay as they can get higher bprices. Sometimes you can find them in antique shops at bargain prices as well.
