John T is correct on the best place to get that helmet, that's where I got mine.
I like the helmet but I am not super convinced it is the right helmet for me.
First, while I have no ther flip ups to compare to it seems rather noisy to me, my opinion. And after flying planes for thirty years my hearing is less than steller, I also went to a few too many rock concerts so it's hard to say (or hear).
And at first I thought that a flip up would be very convient, I never seem to use that particular feature. It seems that I just don't need it.
So while the price link, from John T, is definately the way to go, the other info is just my opinion.
I wish there was a way to test ride helmets, good luck!
