I'm looking into getting into kegging and I was thinking about using the plastic pub kegs as it is what my LHBS caries. However, I can not find any sources for them online. Were these recalled or something. When I do a google search for shopping, only one source comes up. I understand that I should support my LHBS and I probably will, but if these are not being used anymore because they are dangerous or poor quality I would rather not spend my money on it.
