It doesn't seem like too long ago I was in this boat... All the major points have been covered here. Understand that you might be spending multiple hours in this thing, so comfort is essential. With anything you get, run it through some review sites to get an idea of the things you can't find out inside the store, like how noisy it is at highway speed, airflow, so on. If you are thinking about modulars, IMHO Nolan really is your only option. You're staring down $400 easy with this option. I personally have a Scorpion EXO-400 which I love, it's decently quiet at highway speed, and the fitment is good after I removed some cheek pad foam (big ups to someone in OR for teaching me that), and a Caberg Solo which looks cool, has a flip down internal visor, but is louder than all hell on the highway. Just remember this is your head you're protecting here, and you only get one. With helmet tech these days you don't have to go totally into debt to get something sensible, but don't get the 30 dollar Bell special at the Pony either. Hope that helps.
