Hi Bill,
Not sure how much help this is, considering your considerable research, but I have been getting great results with the Rollei-Digibase kit from Freestyle photographic ( http://www.freestylephoto.biz/66016-...ll?cat_id=1001 ) and I don't do one-shot...I develop a bout 18 rolls of medium format per 1 liter batch ( you can make a little more than 2 of those with the kit I linked to.

In short, beautiful results for very little money.
