it is discontinued, so for that reason alone i'd stay away from it. also, it is very awkward to move it after it's setup if there's snow. i own the dx3000. never gets used.
i found this statement below from another site:
Last Year I purchased a Shappel 3000 DEuxe. The Deluxe has the nice Canvas, not a tarp. I like it, but it is a bit awkward to drag. This year I am gonna try the skiis that are available. The Frabill Speed Shack is nice too, a friend of mine owns one. Also a bit awkward when pulling and WEIGHS A TON!! The weight of this is what kept me away.. Put some gear in it and pulling is next to impossible.
