Hey, New to the forum. But I can answer this question.
Yes. In fact I just E-bayed a nice Canon A-1 in fantastic condition. All the foam is in its place and there is NO shutter Squeak. I have the usual 50mm 1:1.4, a 100mm 1:2.8 and an 80mm-200mm 1:4 Zoom Lens.
I had used my fathers AE-1 Program several years ago when I borrowed it for a Grand Canyon trip and loved using it. I have a poster, from an image I took, of a raft going through Lava Falls hanging over my sofa.
And since the advent of Digital cameras I have ALWAYS been dis-satisfied with my pictures, since the cameras I have been using are my wifes Point and Shoots and Kodak Easy Share DX7630.
I must admit, with some embarassment, I have never used a Rangefinder. (let the flaming begin...lol) but have become quite interested in the format.
