Thanks all. Stu: You're right. I've got plent of Pentax M42 lenses and they don't come with viewfinders as they're designed for SLR bodies. Phototone: Don't need a 35mm. My Bessa R came with one.
Kuvvy: I think we're in the same boat together. I was at the point of just ordering the body, as you did, and then I thought, "what good is a body sans lens?" Plan was to get the body before they're all gone, and then save up for the lens (either 25 or 21 - and I've heard sound arguments for both lengths, though at this point I'm leaning toward the 21, as I believe it's RF coupled - what if the L body breaks?).
On the other hand I could order both and be done with it. I'm just gonna have to sell some more stuff. Anyone need a 1951 Zenith Wave Magnet portable short wave radio in perfect working condition? Or a 4X5 Crown Graphic with the 135/4.6 Graflex Optar? Everyone should have one of those...
