The pictured wing is the Sorcery, with their underwing; I have the Voltex IV (Esprit) GT wing, and underwing.
I had several successful transactions with GT-ROM, but have not ordered in some time... I communicated with the owner a few months ago, and he assured me that everything is in order, and he continues to ship product to customers, but some people on this forum have stated otherwise.
For the Sorcery parts, I would probably hit up KANE (Raffi), who would get his parts from DJ (of gt design extreme fame), who would get his parts from Sorcery in Japan.
