I ditched my Arai Signet GT early last year after about 10 years of use. It worked great for years, but it fell apart on me while going 50 mph. Thankfully I was on my way to a bike rally with alot of vendors, so I got to try several on at the same time. I went with the Schuberth C3 Pro. I had some reservations about spending so much on helmet, but I got it at a good price ~$670.
It is so quiet, light, and cool (looking and wearing). All of the controls are easy to use with a gloved hand. I have a big head, so if I can find a helmet that fits, price is not my primary concern.
