Trimble GS200

First time posting here.

I have a Trimble GS200 that has been sitting in a closet for quite a while. I don't really have much of a use for it, but don't know what I could reasonable expect in resale.

Includes heavy duty tripod and Trimble scan targets. In great condition, hardly used. Does not include a laptop.

I don't want to put it on eBay, but I also don't want to expect too much or too little given that it is a bit old. Any advice would be appreciated, and, of course, offers would be entertained as well.

Thanks very much
