Well, your choice is quite open really. You could buy a cheaper MX lid if you're riding mainly off-road. The benefit to them is that they're lighter.
If you want a flip-front lid then you could look at something like a Caberg, however they're generally heavier than a standard lid due to the flip mechanism.
I was in George White's Slough at the weekend and they had HJC Lotus full-face helmets for £25. Bargain.
Does that help?
