Hi Paul, Echoing what Fred sed, you should call up Jansen and establish an account, and get them to explain their wholesale pricing. That said, they sell a kit to refurbish the bench mechanism to eliminate the wobble. It's just a bag of metal bushings and the like, but it's a great way to bring your (Jansen) artist bench back to feeling like new, with no wobble, or at least very little. You shouldn't expect to have much wobble with a new bench from anyone.
