Saferacer has a great selection of name brands at decent prices. I can’t afford a real fancy helmet, but I insist on a name brand. Strikes me as seriously shortsighted to buy some no-name helmet off eBay, for example. I have used Bell for years. The lower end of their line for a full face is ~$300. Also, they come in sizes big enough to fit my giant head. If you need a helmet, you need a full face helmet, IMHO.
