    I believe the benzoxazines are used in high operating temperature applications where polyimides and BMI's are typically used. Tg on some that I have seen are in the 200C range.. Because of this, they have to be processed at higher temperatures either in autoclave processes or high temp RTM/infusion where the resin need to be at 100-110C to have a low enough viscosity to flow. I am guessing that the cost is "aerospace grade" as well...
