I got a One Industries helmet last year and for the $300 that it cost, I thought it was pretty poor quality. It is made by KBC. The Arai that I had was far better. Even though the Arai is more money, it is still a good value because of the quality.
I'm rockin a Fulmer. Not the best, but it works. I crashed a little a few times. I'm getting a new one for 09. Not sure what I'll get yet. I found the 08 Thore force carbon helmets for $159 on a closeout. May go with that. If not I may just rock the HJC. I want a TLD but they be too much dough for my pocket!
I have the O'Neal 309 Avalon. I was somewhat picky on the graphics. I didn't want something plain. Other than Troy Lee and Shoei, O'Neal seemed to do it for me. I tried on a few at the store and the O'Neal helmet seemed to fit better. I was suprised to see the Shoei didn't really fit very well. This helemt has a pretty good fit, good ventilation, and look. I wanted the O'Neal Crisis, but I just found the other day that it has a pretty uncomfortable fit.
