If you don't care about the fact that it's a converter filler then go for Nakaya. It's a looker of a brand. But I can definitely see how some would find them overpriced for what they are.
The converter IS a limiting factor, no doubt. From a strictly utilitarian standpoint I cannot see the Nakaya as an improvement over the Pilot CH 92 but ... sometimes you want to own a work of art!
Horses for courses, to each his own, YMMV, and all that.
