FWIW I don't actually like $10 helmets myself!
I have an Arai shaped head (Baldar Conehead?), and wore an Arai bike lid for many years. When I started sprinting I got it stickered up with the MSA decal, but at every event I would get sh1t from the scrute for not having a legible ACU sticker (it was worn off). So the MSA sticker means dick on its own!
Anyhow, I got tired of the hassle and decided to buy a Blue Book approved lid.
Tried on everything available at GPR, starting with the cheapo Integrale. The Bell range were very uncomfortable, and disappointingly so were the Stig-a-like Simpsons.
As usual it was the most-expensive-one-in-the-shop (the Arai) that fitted perfectly!
That's life I guess!
