i have a storm, and its not really a GS problem. Its a .21 size motor problem. They have such high compression that they grenade pull starts all the time.
I bought the 12v starter box and couldnt think of breakin in a motor ever again with out one.
Its kinda a pain if you stall 50 feet from your box and you have to go get the car and carry it back. Thats where the pull start comes in handy

Id say get the bump box. I got the pink ofna one and it works like a champ.Think about it the $50 you spent on 2 pull starts already you could have almost got the box. Then if you get another .21 im willing to bet your gonna break more of them.
