I rolled off a small 4ft drop + bike and body height, landed head first on a rock, got up and kept spinning to the right. Had to wait 15 mins or so before I can even walk using the bike to hold me up. CT scan showed a nice concussion. Next day I threw out all cheap lids I had, and told the wife I'm gonna spend some money on more helmets, spent about $350 on a road and MTB helmet.
This time of the year, you should be able to find 2012 models on a good sale price. More expensive helmets are lighter, stronger, more vents. Again get the best you can afford, you never know when it can save your life....
I don't think there is much difference between the $40 model and the $150 model. I asked this while in the bike shop and the owner said that they all meet requirements and that's it.
