I think the Marquis dealer is steering you in the right direction on the cover lift. There is a hydraulic cover lift called the CoverMate III that is easier to open and close, but it is significantly more prone to failing, and I personally am not a fan of it. The recommended cover lift from the factory is the Cover Companion, which is probably what the dealer has shown you. The Cover Companion is a super solid lift, nearly impossible to break. It's pretty easy to get on and off for most, flipping the cover over half way and pushing it all the way open once you enter the spa is a good way to do it.
