There are deals out there. Some years ago my wife and I walked into a high end antique shop and I noticed what looked like an eveready case under a counter. I asked the clerk to look at it and it turned out to be a very clean M2 with a 50 Elmar 2.8. The price was $1100 and I commented that was a bit high. The clerk reached under another counter and pulled out another large case. It was packed with 2 visoflex, finders, bellows, large array of adapters, ball heads and 1 Zeiss son at and 7 Leica lenses including a mint 35 v1 Summicron. Also there was an essentially new IIIG with like new 5cm collapsible Summicron for $500. I walked out with the package for $1500 total. I kept the M2 and sold the rest for a clear $10,000+ profit.
I found in another antique shop a very rare 4x5 Baby Deardorff with 210 Tessar in an Ilex shutter and 5 new wooden Graphic holders. The set appeared to never have been used. Inside the GG back there were no rub marks from holders. I picked up the set for $800 and used it for several years. I sold the lens seperate of the camera but in total made about $3800.
I've found a few others and still looking. I just found a Technika V for dirt cheap but unfortunately it's a project.
