I guess that's where we differ significantly in opinion. I consider myself a fan, but I wouldn't consider owning one of these a badge of honor. I would consider it a treat and a delight because I think the design is cool. The rarity means nothing to me, other than making it that much harder to get into the hands of other fans.
Dude, sometimes people just can't afford to buy these things right when they're released. I'm sure you can imagine all the different reasons why this is so.
Oh, and do recall that when the original Low Vis was released, its MSRP was the same as any of the other Valkyries, so unless Yamato is secretly selling some of these after-market, I don't see how they would get profit from higher prices.
