This site has some good info http://www.helmets.org/helmet15.htm
One of the first things they say on every review page is : "We have tested a sample of cheap and expensive helmets and found no real performance differences by price"
"Higher priced helmets usually have big vents, but no verifiable advantage in impact performance. Our testing showed that the sample of very expensive helmets and very cheap helmets we had tested had about the same impact protection"
If you have a consumer reports account I believe there are several reviews on there too but they may be older. But again price had little to no impact on how safe the helmet was in any of the research on either site
Again spending more can get you better performance features, but it won't increase safety if both are CPSC certified (I'm saying cheap is fine, I'm not saying Chinese knock off is fine)
