Todd Tuckey did a video on these. Basically he made it seem like the company that made these tried marketing them to average people to be operators. The company also highly encouraged buying spare boards. This leads me to believe that MANY spare parts are floating around out there.
Considering it's in such nice shape, and don't go for that much, it probably would be easy to track down the parts needed. Todd may have some! It's a nice coffee table in the meantime so you can take your time finding the parts and reassemble as you get the parts. Just my two cents.
