Whatever you do, make sure it fits and is comfortable. Different people have different shaped heads. I found Smith helmets fit me well but cant tolerate a Bontrager for a second.

I recently purchased a Kask cause I wanted something not made in China (there are very few) and I love it. Expensive, but extremely comfortable and the ventilation is far better than any other helmet I've tried. I had a 20% coupon that made it easier to justify.

As someone else mentioned, look for sales on discontinued models or less popular colors.
