Hi, some months ago I bought a rubik cube from a local store and started playing with it. The cube was ok while I was learning how to solve it, but it has always been hard to turn its faces and usually I have to turn the faces perfectly, otherwise I cannot turn another face because it locks.
I am now in search for a new cube. In several pages people have recommended a DIY one, so I was thinking on the Rubik's 3x3 White Assembly Kit. After some search I have seen recommendations on cubes classified by type A, B, ... , E. Can someone explain me what are the differences between them? I also have seen other brand cubes that have been recommended, like cube4you, lubix and another one that escapes my mind. What brand do you recommend guys?
Thanks in advanced
