Look on Ebay for an old Loggy stand. The first Loggy came out where you only needed the base. It hooks to your feet and you shimmied up the tree. The single piece is the lightest around, allows you to attach your back pack to and put it on your back. Its also extremely quiet. I've bought another one not too long ago off ebay since they aren't made anymore.
Here is one below. Forget the climbing aid included with this one. The key features to look for is the base of the stand that touches the tree. notice this one has a smooth arch. For some reason, Loggy experimented with 2 feet extending from the uder support bars that touched the tree. Thats a bad design. This smooth arch is the one you want.

This one below looks to have those feet.
