G15 V1 is the best imo.
Rev2 looks gay ( orange ??), and has removed some buttoms, never mind the cool volume control.
I'm stuck with a G11 v1 though, oh well no worries, I still love it I mainly bought it for the G and media keys ( saitek eclipse 2 wasnt out yet iirc, and there were no other illuminated kb's with media keys out there, which were a must for me as I was way too lazy to get under the desk to my sub and change volume there).
