I have an opportunity to purchase a Sky Ski Pro that is about 10 years old and in really good shape. It is owned by a 69 yr old man who never really uses it anymore as he has sold his boat and his family has no interest. I have been looking on and off for a few years for one, but wanted to get someone else's opinion before I bite the bullet. Judging from the pics, it is in very good shape and needs nothing according to the owner. He replaced the binding straps with Velcro straps as the original straps were too hard for him to put on in deep water. That is the only modification that he has done to it though. Is $850 shipped a fair price or should I just keep looking?
