As I've understood it, the difference is you have the DOT, then M, then SA. DOT is the weakest standard, and the cheapest helmets. M is for motorcycles, and generally is good for one solid hit, then it's garbage. Also not very fire-resistant. SA is rated for multiple impacts and is much more fire-resistant than M, and is of course the most expensive.
