10yr warranty on the headset...go for it.
i personally like the look of the king sotto voce headsets now...by the way, which means the headset your looking at was made before november '08.
chris king also just released a new split ring design at eurobike last week...so you'll be able to get the headset up to date (read 1990's) with a retrofit kit for about $30.
and be sure to be a cool kid and install the KING cups upside down.
