I just purchased a used RB SD. In excellent shape. It came with the 90mm C lens and 120 film back. If anyone has a 220 back (pro s or ProSD)in good condition that is an extra or not needed I would like to purchase it.

This is a move up from the m645 I have had for years. Any suggestions that anyone has concerning this camera would be appreciated. Things to watch out for and the like. If you have the time and would like to give any feedback on personal experience it would be greatly appreciated.
