Welcome to our forum.
Check out this pricing of a Covermate I. Click here for the Covermate I There's lots of people that deal with Roberts Hot Tubs for their spa supplies and it's always great feedback. The item at the bottom of the page looks interesting as well! Steve
There are multiple options but I'd suggest the Covermate I as a good lifter at a good price. I actually prefer the Covermate III on larger spas as its sturdier and makes opening a big cover noticeably easier but you've indicated price is paramount so I'd suggest the Covermate I.
$200 ?? would a pm on this be considered spam?
