4U, head heavy, stiff, but cheap

Hey everybody,

is there a cheaper alternative to the Yonex Voltric Z-Force II? It's currently my main racket. But if I want to have several rackets of the same sort as main rackets, I will need to look for a cheaper alternative. I can't afford more ZF2s at the moment.

So is there any 4U (80-84g), head heavy, (extra) stiff racket out there, that costs less than the Yonex flagship? I'm from germany, but I'm willing to order from international sellers.

Best Regards
klaus
