I ran across a sale on Shoei RF1100 solid color helmets for $250 at Competition Accessories. It's a good price but I don't know much about the helmet other than reviews I've read. Most say it's very good. I don't know anything about the store either. Just thought I'd let you know in case you're looking for a helmet in that price range.
I also found some Shoei helmets as low as $199 for certain sizes on their closeout page
