You might want to post this question in the A-Frame sub forum. Several members in there have same model as you & might be more aware of the market. Irregardless of its near new condition, it is unlikely you will get close to what you paid unless you got a terrific steal (deal)at time of purchase. I would plan on no less (rock bottom, if sale is a MUST) than 30% less what MSRP was at the time.....Getting more is always better!
