But I do like the interlock cocking the shutter and the mirror and rotating the film to advance it all in one movement option that the RZ has that the RB does not.

I wasn't looking to purchase though as I said I am only interested in trading so KEH won't work for me since it's a purchase site isn't it? (Never used it).
The Pro-SD backs for the RB have light traps, while the earlier backs use foam.

And if you don't like having to wind the film, buy one of the "cheap as chips" power backs .
