Carb spacer review for the carb guys out there?

How many of you fellow carb guys are running spacers? I've always wanted to try out one of those badass Wilson Manifolds spacers, but the prices always scared me off. Well turns out a local Factory Stock racer switched to EFI and sold me his spacer for $50 (which is brand new and was $140 new)
