Shen has just done some custom work for me. Just ask 'em- chances are that you can get whatever you want, at ebony-like level of quality, for a low price.
Keith, how do they charge for the custom work, is it by the hour, nature of the work or other?

What did they do for you? I was looking at my 4x5 Shen last night and realized that it could extend another four inches with a modification at the rear. It would be interesting to see how they would do the work. I have a good idea of how it could be done and I could do it but I don't really have the time.

Brad when you find the camera you are describing let us know, I personally would like to see one in a 5x7. I'm looking at the Ebony models, the others are fine but they all have one limitation, short bellows.
