What's your most used/useful machine?

[sodaman]

I use my RC 81 because it is the nicest original machine I have and I can rely on it to vend and cool every time so I use it when I have family over for Thanksgiving and Christmas, although they don't know anything about the machine, they just know they can get ice cold glass bottles of pop from it and most of my little nieces and nephews have not had that experience.  Most popular selections:  Orange Crush, then Nugrape, then Big Red and finally Coke.  Of course I have bottles of RC in there too.
