Heads up all you serious Divair Reg collectors. I ran across this on ebay earlier today and thought I'd post it for anyone who might be interested. This one looks to be in really good condition. Happy bidding!
Just so you can plan for it, the diaphragm will cost another approximately $60 (including shipping from Canada). Otherwise, they are inexpensive to rebuild needing only some o-rings if the soft seat is good.
