I've been using the SHARP website as a guide on what to look for. I set up the search to search for helmets with a 4 star or higher rating and a price range between £100 and £200. I do it this way because the real cheapy helmets seem junk and none of the cheap ones have a sun visor. I set it higher at £200 because the prices on the site is higher than what I can find most of the helmets for.
This link will show you the same results I get. I've narrowed things down a bit and my list has the following helmets on it so far:
Caberg V2 407
Caberg V2R-R
AGV Stealth SV
AGV S-4 SV
Shark S900
Nolan N85
Lazer Breva
The Caberg helmets both have 5 star ratings, but my past impressions of Caberg were always that the quality wasn't that great and for some reason I think they are noisy
The trouble with the AGV helmets is that they tend to be too close to my chin, but I will try them on anyway, 4 stars.
The Shark S900 looks good for the price, one of my favourites at the moment. I might be biased as I had an RSI before that was very comfy and the good lady also has a Shark that is very comfy (definitely on par with the Qwest for comfort and fit), 4 stars.
I've never considered a Nolan helmet before, but the N85 looks like a good helmet for the price.
Also never considered a Lazer helmet before, the Breva looks decent.
If anyone has any suggestions to add to the list, please let me know and I will look at them (must have an internal sun visor.) The HG-15 doesn't seem to have an internal sun visor, else it would be on the list, it looks like a decent helmet.
So now I'm looking for anyone that has any of these helmets to point out the good and the bad about them. Things I'd specifically want to know about is how noisy the helmets are, any whistling or rushing wind noises and such is something I want to try avoid (also if I turn my head.) I doubt the helmet shops will allow me to go take a ride with a helmet so the noise thing is something I will have to judge from other people's experience, even though it is something that everyone has different opinions on. Would also like to know anything that I would only find on a test ride, eg. how well the visor seals, if any of them leaks water, if vents work or not, etc.
