Time To Buy A Helmet

I should have been more specific when I posted my question. As I said, it was the 80's when I last bought a helmet. I thought maybe things have changed when I saw the $27.95 bucket. After all, you can buy inexpensive, quality stroker kits and many other products. I'm not putting my head in an inferior helmet, for sure. My head is worth more than $30, if a $30 helmet is not good. Is my head worth $100? $300? $500? My wife might answer that! LOL! Thanks for the advice. I'll be shopping for a good Snell.
