Might be too much $$$ for some but the combination of lightweight, good ventilation, huge eye-hole, and the padding kit to custom fit it for your noggin could make it a good buy. And it is DOT, ECE, and NBR-7471:2001 approved.
I couldn't find it for less than asking price; but Revzilla had it for the same price as everybody else with free shipping and $25 off my next purchase. They also took off $10 from a previous purchase. It is over a pound lighter than the full-face I've had since I bought the bike in '08.
