Bought this from another reef member for my build but decided to go different direction. It's a version 2 drum. Body and drum is 3 yrs. Top motor is only 5 months old. The complete unit cost $260 USD new. Replaced motor with the new version for $100 USD. The replacement motor is completely silent and of better quality. Looking to get $140.
