Dynobyte,
I got one of those last year. Pretty comfortable and relatively decent ventilation. You can wear sunglasses like Raybans with no problem with it on. Seemed like a pretty value.
I got lucky and my hat size plugged into the sizing chart worked out to be a good fit when I tried it on:

You might also want to consider getting a balaclava:
