I too would love the opportunity to buy an HE-350. Even if it doesn't quite perform to the level of having individual HE components, it's a bit more economical and flexible. It costs about $1000 USD more (give or take) per unit for the HE-version of the same product, whereas it was, what, $1580 for the 350? Four components could benefit from it, and there's less concern with leaving it on all the time, versus the other HE units (though I realize the most recent versions can be left on all the time, provided the ambient temperature in your room/home isn't too high). By the way, earlier this year, Kingwa mentioned the possibility of producing a run of HE-350s, provided a 'group-buy' scenario materialized, but not enough people had expressed interest (I think he said he needed 50 units for it to be viable, but I could be mistake).
