Scattante was the Supergo house brand, and when Performance bought out Supergo recently, Performance picked the brand up. Martec makes their carbon fiber frames along with EPX, Kestrel, Pedal Force, Argon, BP Stealth and some other manufacturers. I think I read on Bikeforums that Advanced, Topkey and Martec, all in Taiwan, make something like 90% + of all the carbon bike frames in the world.
You can read a lot of positive reviews on the Scattante brand: most people think they offer excellent componentry and build quality at a really good price. The downside is that the sticker on the side does not say "Trek" so it is lacking in the snob appeal. But as a middle-aged, straight, married healthcare executive, I have pretty much given up caring about such matters. If it works well and is a good value for the price, that is all I care about. Kind of the same reason that I have bought some Taurus handguns in recent years, even though I can afford whatever I want.
