I bought one from a fella in Alva Wyoming that is spectacular. It weighs about thirty pounds. It cost me $90 about a year ago and is worth twice that to me. It folds to about 3" thick, 18" wide and about 4' long. Has a seat built in and is very stable. He even throws in a set of sandbags with it. Here is his address.
