It would make it easier for people to recommend a helmet you might like if you give a few details. Are you leaning toward a particular kind of helmet (flip up, full face, dual sport, etc.)? What are you looking for (value for money, ventilation, cool looks, etc.)?
Anyway, I've got a Nolan N44. It's a "modular" helmet (in the sense that it can be converted into different configurations).
Mid-priced, good build quality, really good ventilation and visibility, but a bit loud (although I wear earplugs almost all the time, so this doesn't matter to me as much). I highly recommend it, although I wish there was a true full face version of it but with the same huge eye port.
