I stopped by "The Home Brewery" in Springfield MO today. I wanted to pick up a few more ball lock kegs. The 12 I have are full. They used to sell them (Last Fall) for $35. Today, they were $49.99 and really beat up. I didn't buy any because I thought it was crazy to pay for kegs that looked like they were in a tornado. The owner's wife told me that most people will have to switch to pin lock because that is all they can find now. So why is that?
Steve, I think it's just supply/demand. Ball locks seemed to be the first choice for homebrewers, and now that Pepsi doesn't use them anymore, the supply is just drying up. When I first started only 3 years ago, you could find them on Craigslist all day long for $25-30. Now people want $50 for them.
You know what that means? Time to stock up!
