The upright is a cooler cabinet for sure, but this is way rarer, and it's a rare example of a popular title.
Generally, cocktail h8rs want this thing to be worth around $300-$500. To me, it's a $800-$1200 machine. This one, closer to the latter value (it's nice).
I bought the cocktail version in 2000 for $500. Sold it for $500 2 years ago. Yeah, they're somewhat rare no doubt, but I wouldn't pay more than $500 for one. Actually, I'd try to find an upright if I ever wanted another one.
Tapper CTs and many other CTs are like cabaret machines: so many people say they should be cheap. So many people say they've bought and sold them for cheap, etc.
Then, they turn up for sale on KLOV with a big asking price. Funny how that works.
