Hey Steve, I actually just replaced mine a few months ago. ( and I don't know if you were aware, Marquis actually replaced my whole tub in 2008 because of crazing in the shell, but my cover was still fine so I held on to it) I felt that I got a real long life out of my cover, so I stuck with the brand through my dealer. I believe it is a Sunstar..That way I was sure it would fit perfectly. I'm hoping to get the same long life out of this one. I think I will be replacing my cover lifter in the next few months and again, I will go through my dealer.
Hope all is well with you..I miss seeing you on here
