And aura, when I said 75 bucks, heck there are $45 helmets that are pretty darn good, with good ventilation.
Yep, I buy literally the cheapest helmet I can find (okay, so I avoid the pink ones and might splurge an extra $5 on one with a visor) and even that is lightweight and ventilated enough. My current helmet is this one, which I think I might have paid $30 for (on sale):

Incidentally, I bought this helmet about a year ago. I still keep my old helmet, complete with cracked foam, as a sort of
memento mori.

I like these ideas, although I'd also like to have some kind of bracket for video camera(s) too.
