I don’t quite understand the OP’s desire to buy a “beater” in the first place. A Leica would only be recognized by a very tiny part of population...such as readers of photrio. Most of the contemporary population has no idea that film is available, let alone recognize a Leica.
The lessons to be learned here: buy one in the best condition you can find (but still be prepared to have camera serviced); carry camera in some kind of case (my cameras have survived drops, falls, and bangs while in some kind of case); watch your step.
I have bought “bargain “ cameras from KEH, and could never figure out why so classified. Recently, from a reputable dealer, with a choice of one model, I bought the one recently CLAed for $100 more. Shipping alone for a CLA would cost almost as much.
