I may need to replace the wheels on my sea stairs. Has anyone replaced the wheels on their Marquipt sea stairs from a source other than Marquipt? I don't mind paying their proud prices for the stuff they make themselves, but as I learned when I had to replace the controller on my tender crane, many of the parts on their equipment they just buy from retail suppliers and mark up 50%. For example, the winches and controllers in most of their cranes are just the same Strongarm brand stuff you can buy over the internet.

Thanks
