i haven't read anything but good reviews. scorpion is a baby int he market but already a heavy hitter. i think that brand will be around for a long time and only improve as time passes.
If it was me, which it was at one point, HAWK Helmets from Leather Up.com 100.00 bucks flat black modular/with flip down sunshield, not badly noisy, but I don't have much to compare to, for 1 Benjamin can't go wrong
I have a Scorpion Exo500 Other than fitting tight on my cheeks I dig it. XL fits my skull best but went with an XXL so my chubby cheeks don't get squished into my eyes.
