Some of us who have bought them are happy with them. I bet that none of us are happy with what we paid for them! I'm glad there are plenty models and manufactures to choose from that way we can all be happy. One plus of trying one of the other tops first is that if you are not happy with it and want to try something different you won't take as big a hit financially as you would with the sling shade. Even though I haven't seen any used ones for sale I wouldn't expect the resale to be too good. jes my .o2
I also think that re selling the other tops to recoup part of the cost would be easier with the aftermarket tops than with the slingshade - unless you want to sell the roll hoops with it you are limited to buyers with a newer slingshot
