Electric chair sales advice

[9000ft]

So I'm posting this in the equipment forum instead of sales because I'm really just looking for some input from the crowd. When I left rehab in 2005 my OT convinced me that I needed an electric chair. Since my insurance would pay for only one char I had them buy the electric while I payed out of pocket for my manual. Basically the electric has gone completely unused and lived in the garage since day 1. It looks brand new and has had almost no use. I'm thinking I want to sell it and buy a 2nd manual for back up instead of the electric. Since I know so little about electric chairs I was hoping some folks who use them can help me put a price on it. It was $11,000 new and I'm planning on posting a flyer at Craig Hospital where I did my rehab. Any input on the price would be appreciated. It has a Jay2 back and Jay2 deep contour cushion.
