I own a 7X17 Chamonix and a 20X24" camera by Richard Ritter so my comments may be interesting.
Chamonix cameras are light and very well built. Aesthetically they are among the most beautiful cameras I have seen. Richard Ritter cameras are very light and well-constructed, and also allow setting up the camera for shooting in both vertical and horizontal orientation. They are perhaps not quite as "pretty" as Chamonix cameras, but they are very "functional." The ability to set the camera up in vertical orientation is in fact a big plus for the RR cameras.
Regarding the 20X24 format, I looked carefully at the features of Chamonix and RR cameras and decided to go with the camera by RR because of its very light weight, greater bellows draw and reversible back. The Chamonix camera that I considered did not allow for reversing the back, a serious negative to me for 20X24 format. I understand that Chamonix is now offering a 20X24 with a reversible back, and more bellows draw, so the scenario is not quite the same as when I made by choice.
The RR 20X24 is both very light and rigid, and I can also use it with a 12X20 reducing back. Focusing is not ideal because the rear worm mechanism does not cover much space with a turn, the result being that the image does not "snap" into focus as I would like. I would definitely like to have a faster moving focusing worm for this camera.
