It's hard to stay away from ebay.
Dang, that's a huge image!
Hey Bob. I see you have an old Nicro stainless back there. I have one too, my mother in law picked one up at a local goodwill store for about $5. The old rubber seal is a bit shot; however I put saran wrap around it and it seals great. The metal filter mechanism on it is ingenious.
