I bought one used for $2500 from my local dealer, then sold it 2 years later for $1500, it had everything, including the cruise control and even an added lighting system that ran on batteries that was installed under the shelf that holds the pantographs.
Worked great as the demo set up at the dealers and worked great for me too.
I sold it because it was simply taking up too much room and I had it in the living room. The machine needs to be oiled frequently if you are using it frequently, that's the only sort of negative thing I can say about it.
