The soda parts arrived thursday. Took approximately 2 weeks from the day I ordered it from sodaparts.com until arrival. Here is a brief "unboxing":
Three massive boxes. Not shown, is the 2.5 gallon box of Coke they also sent.
I upgraded to the 10lb bottle of CO2 for an extra $30. I suspect I will be glad. You can see here the syrup pumps, the carbonator, the tower itself, and the CO2 bottle.
And here we can see the chiller itself. It's big, and it's super-heavy. Yikes.
