How long are they effective / safe (assuming no accidents)?

Almost forever, there is no expiry date on helmets.

What’s the difference between a $40, $80, and $200 helmet?

No difference at all. Cheaper helmets offer the same amount of protection as expensive helmets. Expensive helmets are just a fashion statement


Would you ever buy a “gently” used helmet?

No I would never buy a used helmet because there is no way of knowing what the previous owner did with it.

Any recommendations on where to buy a helmet?

Bike shop or any sporting goods store which sells cycling gear.
