Is the Gait air d really worth $300 dollars?

I'm a jv defense player on my high school team, and just got feedback from my coach that I was on the edge of varsity. She told me that I need a new stick which I could agree more with. I currently have the Brine dynasty Warp pro stick, the stick has a sown pocket so I can't adjust it what so ever. I know I need a new stick, but is $300 dollars really worth it, I just feel bad for my mom using that much money. Is this really worth it? Or are there better options!
