The best price you will find a ghost cube, and you get all the same turning quality. As a long time buyer and collector of twisty puzzles I want to say buy the Mefferts, to benefit those companies and the designers. However, I also know that life on a budget is a real thing and when this is an amazing feeling, turning, looking, puzzle and is almost half the cost I must recommend getting it. With the money you save you can buy another puzzle. The ghost cube has a great history of development, it is the pinnacle of 3x3 challenge thus far, on par with a latch cube, but act very differently by changing shape and being colorless. A perfect use of $20 for any puzzle lover.
