Time To Buy A Helmet

I haven't bought a helmet since the 80's. I was just poking around the web and found one for $27.95! DOT approved, not SNELL. NHRA requires SNELL, don't they? I want to get a good one, but I don't want to spend a bunch. Same old story. I don't race much and I don't need one for anything else.
