Helmets are costly, but cheap compared to the alternative.

Ditto to that. Your helmet did its job by falling apart. Like the crumple zones in cars that keep the energy of a crash out of the cab where you're sitting. Even if it hadn't broken, you now need a new one. Get one that fits right and feels right, so it's where it needs to be next time you (G-dess forbid) need it -- not slipped out of position, and not left back at home.
