Im looking for the cheapest racket that has a stiff shaft if anyone can find me one online let me know
At £30, you're not going to be looking at specs ... very stiff rackets are not going to come so cheap (new). If you don't want very stiff, only stiff (a bit ), then just go to your local sports shops and flex a few shafts.
Yeh, what Solstice said. Hop on down to Sports Direct, they'll have a ton of cheap Carltons (and Yonexes) on offer and have a flex of the shafts. I have a bunch of Carltons and an equal number of Yonexes and for my rackets the Carlton's are stiffer for the same flex rating. i.e. a Carlton Flexible is half way between a Yonex Flexible and Medium Flexible. One of my Carlton's was reduced to about £20 ish when I bought it, it's stiff shafted and light with head light balance. It's actually a suprisingly good racket but it can't take more than 24lbs tension without vibration and distortion becoming a problem.
Apacs Slayer? Apacs sports selling slayer 88, 95 and 99 at discounted price. I've tried the 99 and it was nice. Stiff shaft.
I think the VT9 is a pretty stiff low/mid-end Yonex so it'll be comparatively cheaper, but it's not going to be under 30 GBP..
