Can't help with your helmet selection but you might check with Vick Racing on the Southeast side of Fort Worth. I bought an SA2000 open face G-Force helmet from them about 18 mo ago. He was closing it out and I think I paid around $100 for it. Even his regular prices were good for the newer (at the time) SA2005 helmets. Super nice guy. He even coordinated to meet me and open up their store on a Saturday so that I could pick it up. Their website is www.vickracing.us
