Where are you at? I have a yuxin 5x5 that I would sell you, but if it's going to cost theCubicle $16 to ship the springs to you I doubt I could do much better on the whole cube.
UK, I have a yuxin 555 but I'm not really willing to sacrifice mine as my wushuang locks up too much and weichuang is really slow (at least mine is) so its my main atm. Yeah it probably would cost quite a bit
