Long shot but does anyone on this site know much about bowlers? Older puck style bowler, not a ball. Original owner donated to church <year ago in working condition. Church had repair man come out, fixed, and now doesn't work again. Seller thinks it's some fuse that's blown (no idea). Pictures look to be well taken care of as original owner was non commercial. Original papers, warranty card, and manuals are all included. Currently it doesn't work though.

What are these things worth, working and non. Again, this one currently does not work at the moment...
