Welcome to our forum.
Well, this is old, you may have already bought your lifter. IMO, the Hot Spring lifters are every bit the quality of other lifters. I like the way they fit and the way they install to the side of the cover instead of a bar across the seam in the middle.If you haven't bought one already, go for it with one of the Cover Cradle lifts.
We're getting ready for the spa delivery so I called my dealer to 'deal' on the price of a cover lifter. She told me there was one included with the spa. Surprised me!! I guess by paying their asking price has its advantages. $400+ for a lifter (HS) as a throw in, sort of, I'll take. Thanks for the recommendations though.
