I have a Summit Viper for sale that I only used 3 or 4 times. It sells for around $280 or so new. Weight limit 300lbs, platform is 20"x283/4", will fit trees 8"-20" in diameter, has nice padded backrest and seat,backpack straps and comes with a harness. Heres a pic from the web, but mine is exactly the same. I have no idea what the shipping costs are but I will find out. I am also willing to meet if its within a reasonable distance from central Jersey. I am asking $175
