If you're selling them, you can expect to receive about $1500-2000 per machine unless you can find someone to purchase them who has no idea of their value.

They can be bought new from Red Bull through local distributors for approximately $2500 a machine. So if you price them any higher than say $2000, it wouldn't be worth it to anyone already in the business to buy from you when they can buy them new directly from the manufacturer.

Best of luck...
