I wouldn't recommend one without trying it on first, they all fit different.
I have used a troy lee d2 and troy lee mx lid for the last 5 or so years (overpriced for what they are tho), perfect fit for me, tried a 'the' on last year and I didn't like the fit.
J.E.James are doing some mega deals on 661 helmets at the minute, around half price off them.
I tried the 661 flight warp on in their shop the other day, fit and quality (for 89.99) was good but its more of an mx style lid so heavy if your not used to them, they do cheaper/lighter ones tho.
I also like the look of the new giro and bell, and the fox ones seem pretty good for the money, not tried either of them on though.
