+1 to AJ - this time of year you're only going to find what are typically imported pods in the "popular" category for the general public - not necessarily your favs. So generally for pods of any heat level you're going to be limited to jalapeƱos, habaneros, serranos, and poblanos, and maybe a couple others, unless you find a specialty store that's selling for someone with a serious greenhouse setup. But consider that if you haven't ever made hot sauce before, it might not be a bad thing at all to experiment with some of the more common pods just to get some experience - not to mention they're less expensive if you create a batch that isn't quite what you want it to be.
