I would say with a bit of ingenuity and some spray paint, you could build one yourself for a lot less than they are asking. Neatest one I saw at the QDMA was the electric lift tree stand.
Read the Q&A- it's foam! Use the foam you use for insulating around windows, etc., cut and sand, paint
Man could mold one out of foam I suppose...I cant see 3Gs for this but it is pretty cool. Someone will come along and nail it down for around 500 I bet.
That is cool, but very exspensive! What if you used the planks from a mill when they cut the bark sides off the logs? Im thinking 50 bucks for a hell of a blind that may last years. Now mobility would be a different story.
