For Trade WTT: RZ67 Kit for Mamiya 7

Just gauging interest in this--I have a RZ67 Pro I in good working condition, two 67, 645 and polaroid backs, and an assortment of lenses:
50mm, 90mm Sekor K/L, 110mm f/2.8, 127mm f/3.8, and 150mm.

It has served me well for 2 years, but it's time to change things up a bit. I am looking for a Mamiya 7 or 7ii with pretty much any lens--the 80mm f/4 or 50mm in particular.

Thanks for your time.

Any interest in selling it?
