I think it would be best to define "affordable" at this point. What is the maximum you are willing to spend on a good quality camera and lens? How far are you willing go money-wise if the perfect camera became available? Over the years I determined that rangefinder cameras were best suited for snapshots when in my hands. So, I have never found myself spending more than a couple hundred dollars on a good rangefinder. I'm sure there are others that wouldn't touch a camera that cost less that several thousand. But, in my opinion Adrian hit it on the nail. Get that price narrowed down.
