Good source for Snell 2000/05 Helmet?

[HIFI]

Thanks, I am going to a racing shop also, but if I can save considerably more money, I may order over the internet.

I agree about the value of my head; however, if it is Snell SA2000/5 certified, shouldn't it have been through some pretty decent testing (not to say they're all equal, but...)? I'm totally ignorant here, so correct me if I'm way off base.

Also, what are the pros/cons of open face vs. closed?

Oh, and I'm 6 foot tall, I'm assuming I'll pass the broomstick test??
