I have a Summit extremely light climber. I think it is the bowhunter backpack model. It has a flip up seat and a hand climber which you can also use as a seat by taking pad off regular seat and putting it on the climber. I've used it both ways. VERY comfortable and like I said VERY LIGHT. I'll sell it for $70.00 plus shipping which I am guessing would be around $40.00 . Parcel Post will be the cheapest. Am selling because I got the fold flat Summit which I actually leave set up to carry, no real benefit to it being folded flat. My 15 year old son and I will never use anything but Summit and i used to be a diehard API man.
