Ryan,
First off, Welcome!
Most soda pop machines differ in their physical "footprint" as you well know. If you are looking for a machine that is not quite as wide as your other, conside a Cavalier 55 or a Westinghouse 44. The Cavalier 55 can be found in a single drink and 2 drink version and has an electric coin mech and vending mech. The Westinghouse is single drink and has a mechanical coin mech and vending mech. They can both handle up to 12oz bottles and can vend cans with the proper spacers installed.
They are both thin profile machines with the Cavalier 55 being 16" wide and the Westinghouse being 18" wide.
I have owned both of these machines, still own the Cavalier 55, and can tell you that they are both quite nice and easy to work on. The machine on the left is the Westy 44SK and the machine on the left is the Cav 55.
Just my two cents!
