Well a good friend of mine does demolition and finds a couple a year when tearing down rental units and such. I'll make them available to those that need them when he give them to me. But no timeline or anything on this, it's totally hit or miss.
Just ask around to friends though, my fiance's dad has known I've brewed for a long time, and just last thursday mentioned to me he's got a keg that's sat in his second garage for about 5 years! When I get it, along with any kegs I get, I'll look at what I currently have, and if the new one is better I'll upgrade my existing unit and make old one available to a club member.
I will have one that is currently my boil kettle available soon. It's well used, and sorta beat up, but it's just used to boil wort, and already has a weldless fitting and the top cut out!
