Please, please, please stop making pointless threads about studio cubes.
Studio cube - not adjustable, nice cubies, turns ok, can be quite smooth
Rubiks DIY - adjustable, good cubies, turns well, highly regarded.
I find that the studio cube cubies are quite good for hybridising with.
You can buy the studio cube from puzl.co.uk for around £10.
The Rubiks DIY is from rubiks.com, and more expensively from cube4you. I dont know how expensive they are.
