^^ Very true. There are deals to be had when it comes to purchasing a helmet. $100 or $150 is not an unreasonable price...
Depending on your activity.
To SK's point, and yours, if you intend to take a car to a track, then you WILL need the SA rating.
So, if that is part of your plan, then spend the extra money (within your budget) and get the SA rating.
