At Cost Plus/World Market stores they sell Virgil's in genuine metal mini-kegs, tap and all. I keep trying to convince myself that I want that much root beer, because it would be great to have.
I actually bought one of those. Very good root bear on tap, but it got pretty flat toward the end. I saved the mini-keg. Now I use it as a gag when I say I'm gonna go get a can of root beer. ; )
