There are a few other options out there past the Varis which is very nice but a little pricey. Challenge has their nice trunk which is not too CSLish ish and flows nicely and ModeCarbon has advised me that they have a spoiler and can do it in 1x1 if I want....just waiting on pics.
I am providing this info so that the guys looking for 1x1 spoilers have the info at hand.
