rubik's brand 4x4x4 (at least the new ones) are not made for speedsolving, in fact, they aren't made for demonstration of your skills either. They're just for mindless twisting, if you do anything else it will lock up, and hurt your arms.

I agree. Prolonged use could potentially damage your health. After using a store bought for a few weeks, I suffered serious pains in my hands, even after short sessions using one.
Although I've long since moved on to greener pastures, the trauma prevails.
I feel like I shouldn't be plugging my store like this for some reason, but I suggest the DaYan +MF8 4x4 (world record cube, and cheaper than X-cube) and you can get it at my Australian store: http://kubaroo.weebly.com/
