[LargeFormat] Jobos for 5x7?

[Rich Lahrson]

Hi Mike!

      I've checked the Jobo webpage.  I like the CCP-2 overall.
It handles 5x7 negatives six at time and can even process large
prints and films.  I'm trembling at the cost of this new, but I
don't feel used is best for this, but it depends....
