90's Heiwa "Mahjong Story"

[dirtypair]

So there is supposedly the first LCD table ever, named Mahjong Story in 91, which then continued with a successor called Lemon Pai. I'm really interested in getting ahold of either of these machines, but particularly Mahjong Story as the sound of playing it is really nice, and it's a cool piece of history.

But I'm not sure how exactly to get ahold of one outside of just checking yahoo jp auctions, how much these era of machines are worth, or what the pitfalls that associated with the earliest LCD machines might be. Is there anything important I should know or consider while looking for one? Thanks.
