What are you looking for? If you want skmethjng light I can recommend a nexx XR2 carbon. Right in your price range, one of the lightest helmets on the market and it also has a MASSIVE viewing aperture. I also stumped up the extra 30 quid for a tinted visor to swap in on sunny days.
My Nolan N103 helmet (old) is good as well, but it's a heavy brute. The flip up is handy though, as is the drop down Sun visor.
Here's a short review with pics of my Nexx

(Disregard what I have written about sizing in the article, I originally said buy a size up, but after wearing mines for some time, mines is now a little loose so the sizing is probably accurate now)
