Echo Deerdust. There are several good designs, but all are going to be dang heavy. Strong-Built makes a good one that is reasonably priced. Ol' Man's are really nice.
All are going to be way too heavy to haul in-out for any distance on a frequent basis.
As for erecting ..... here's a trick that helps me ... but I need a buddy. (I can set one by myself but it is a chore.) Most will come with two straps that tie off near the top of the ladder and criss-cross behind the tree, then tie on to the lower section of the lader as part of the support system. If not, I suggest you buy a bundle of woodsy colored rope to make your own. This helps sabilize the ladder and can serve as a "back-up" system should the main tie strap fail. Attach these straps (ropes) high up on the stand ladder. Lie the assembled stand on the ground, stand front down with the base of the ladder 3'-4' from the tree. Have your buddy stand at the base and grab each strap. Lift the seat section off the ground and have the buddy tighten up on the straps, while "scotching" the left and right ladder vertcals with his feet. As you "walk up" the stand, have your buddy assist by tugging the straps and help you align the stand to the tree. One against the tree, level the stand seat, with the stand off support arm in place. Tighten these two straps and you'r good to go to carefullly climb the ladder and install the main security strap.
As a matter of safety, if there is not a second strap supplied by the maker, I install another.
