This is my first ever post on this forum so excuse my amateur ramblings. Only been on the circuit a year, but have managed (in my own time!) the 2x2x2, 3x3x3, 4x4x4 and just recently the 5x5x5. Had insisted on the 'purist' approach and bought purely Rubik products. The word on the street is Dayan. Just bought a Dayan 5 Zhanchi 3x3x3 and a Dayan MF8 4x4x4 to replace my already knackered Rubik equivalents. Will let you know how I get on timewise!
