I've seen Chris' GS first hand since he is local to me and I actually know him. The kit appears to be solid and pretty good deal if you ask me. I didn't catch a ride in it since we were having a BBQ and I was one of the host. I'm sure if any of you want me to, Chris can meet up with me and I can test drive it then give you my feedback. (Ummm chris you have full coverage right

). Hahahaaa
Being a former GS owner (GS400 and turbo'd GS300) and now a LS430 UL, i think I can give you a pretty good overview on the differences. So Chris hit me up if you want to meet up.
I'll be at the Funkmaster Flex show this weekend, don't know if your going.
