If you are a Leica Collector, and HAVE to have the red shutter curtain version and cannot rest in peace until you do, yes that was a bargain.
If you want the best Screw Mount Leica for the money, the IIIf is better. I believe (have read) that it incorporates the ball-bearing shutter pioneered with the "K" model during WWII. The IIIg is the best of the Leica Screw mount cameras, but goes for ~$1,000 for a user. The Canon screw mount cameras have better viewfinders than any of the Leica screw mount cameras. If you want the best "shooter" for the money, and want a classic camera, the Canon 7, Canon P, Canon VI-L, and other of the Canon's are the best bet.
I try hard not to give into the "But it is the rare version with tick-marks engraved into the aperture ring therefore costing OODLES more than the one with just "Pat Pending", but is identical in every other way" mentality, but it is hard. I will pay "a little premium" if I recognize a camera or lens with a "deviation" that is more cosmetic than functional. A red curtain does not do it for me. For 10% more than a comparable IIIf, fine. More than that, its not for its picture taking quality!
