Ok. If you want a REAL rangefinder and one of the best 50mm lenses you'll ever encounter, try this combination: Canon P rangefinder; Canon (or Canon Serenar) 50mm f/1.8. The Canon P is a beautiful classic Leica-Thread-Mount (also known as screwmount, SM, and M39) camera with a very good rangefinder/viewfinder and great weight, construction, ergonomics. And the lens! It still amazes me.
If you watch carefully you can get each for a little less than $200 though you'll generally see them going for $250-260.
This is a camera you could work with for the rest of your life.
Other absolutely fantastic affordable lenses for the LTM mount: Voigtlander 21mm f/4 color skopar; Voigtlander 35mm f/2.5 color skopar and the Canon 80mm f/2 Serenar; Canon 100mm f/3.5; and the really amazing Canon 135mm f/3.5. Those last two, don't confuse the f/3.5 with the inferior f/4's.

PS Check out KEH.com ALWAYS, before buying from eBay or elsewhere. They currently have a Canon 7 (Canon 7 has a meter, but often unreliable due to age; Canon P has none) for under $200. If they say it's in EXC condition, it is. Their BARGAIN (BGN) condition stuff is usually pretty flawless looking. Page is here:

PS Don't worry about "wrinkled curtains"as this is common in Canon rangefinders and almost never affects their functioning.
There's also a Canon P on eBay looking good, and if you go to the seller's other items you'll see an identically priced Canon 50mm f/1.8
(I have no relationship to the seller, though I've bought from them and they're reliable; nor to KEH).
