I have a Canon L-1 that is very similar to the Canon P. $200
I've owned Leica IIIf RD, Leica M2 and and Canon L1 (very similar to the P) and the Canon is a joy to use. The Leicas IIIf are hard to load hard to wind and rewind. I used the L-1 in addition to my M2. Film is loaded by the back not like the bottom like on early models of Lieca and Canon. The seperate viewfinder/rangefinder 35mm, 50mm can be achieved by a flip of a lever. I have to say the Canon has good built quality.
If you have questions, or would like a description of the camera. or would like images of my camera Canon L-1 let me know.
