I have used the Leica M4-P for several years now. I believe of all of the M's they are now and for some time have been the best buy. They have steel gears and are made for the motor winder which I do not have. There are 6 framelines in the M4-P. They are: 28, 35, 50, 75, 90, and 135. They are very fast to load like many of the modern M's and they are somewhat available. I have done a fair amout of street Photography and I always used the Leica. Set on Hyperfocal they are very fast and accurate. As a suggestion try Jimmy Koh, a very reputable dealer in Bellmore, New York. Koh's Camera for his website. Ritz camera also had some a while back, and may still.
