yeah, the Troy Lee ones are sick.
I had a Boeri Big Mountain Fullface a few years ago. It was really too much to wear everyday. Protection was great, but it was too hot and heavy to really wear comfortably.
I've thought about getting the Giro Flint SC. I actually got one, but the size was wrong and they were out of my correct size, so never got to use it.
But, as far as any everyday fullface a lot fo people love it. Good venting, fullface is removable, light, and protection is still good.
Im pretty sure there are (or were) a bunch of Flint SC on ebay. For an everyday helmet that is where I would look.
If you want serious protection, though, the Troy lee or the Mad max are probably the best.
