It also matters which Leica!! In the U. S. they are designated by Roman numerals I, II and III, at least from the 1930's on. The III (usually followed by a small-case letter) is the one with the slow-speed dial on the front. The closest Zorki to that is the Zorki-3. I have two of them (Zorkis, that is!!)
The Leica II had no slow speeds, therefore no front dial, and the Leica I had no rangefinder - it was used primarily for scientific applications.
As noted above, the Zorki-1 is a facsimile of the Leica II. I also have two Zorki-1s, and it's really surprising, at least to an SLR user, how compact that camera was.
If you want to order through e-bay or whoever, be double sure to check the responses from previous buyers - that gives you an idea of the reputation of the seller. Since the orders usually take around two weeks to arrive at your doorstep, you don't want to waste time.
Another tip: Totally ignore the word "rare" applied to a Zorki, except maybe the Zorki-2, which wasn't in production very long.
My own take is that, as time has gone on, there seem to be fewer Zorkis, Kievs, FEDs, etc. advertised. So you want to get in line.
Here in the U. S. one of the best to deal with is Fedka in NYC, run by a fellow named Yuri ( I won't even attempt his last name - he's from Ukraine.) He is very dependable, and I've bought a couple of cameras from him. He goes over them before selling and knows how to make sure they are in working order. His e-mail is

Keep in mind that Zorkis are NOT Leicas, and Kievs are NOT Contaxes. There are many discussions about workmanship, which seemed to vary by how much vodka the comrades comsumed the night before. But the Soviet lenses do have a good reputation.
Good luck in your hunting.
