Hunter's View stands? The stands they sell in Dick's Sporting Goods, etc???? They are okay for a lmited budget. They are made in China and are all steel (steel = heavy) and prone to bang/clang unless tightly secured to a pack.
Thenew type of ladder/hangon/hybrid stand that I have seen get real good reviews is from API. It's a newfangled retractable ladder style stand from Bass Pro Shops called an API Retractable Packmaster:

If I didn't have a Summit Viper X4 and if I didn't want a climber, this is the stand that I would seriously look at.
