I saw a few come out of a container 9 months ago at my friends farm and they both went for apx $2500 tops. They do look a treat when u re-powdercoat the legs n siderails different colours to suit the golf theme, I saw one with freshly done grass green legs etc and it looked terrific.
Quite a few parts avail for this model. I think from memory translites were a issue, but most other stuff was Ok. Very popular in Japan, this model is.

Although they are a later dmd model, they are not that well known here, but are quite fun. I would give it a 7 out of 10.

A game like Congo is a much better player, a 8.5 out of 10 (another sleeper title) but definately play Gofers before buying.
Good luck with your search.
