Well, yes and no. The Hryahlavolamy puzzles (from the Czech Republic) are based on the megaminx but oh so different.
You can see three of the puzzles made by this company in mid-turn. They are tiny little things. I don't have big hands, but anyone who does will have difficulties turning them. Heck, for that matter, the glowball (bottom center) I find very difficult to move. There simply isn't enough to grab onto. The puzzle to the top left is a bastardization of the flower and the metamorphix. Top right is simply called the flower.
If you can solve a megaminx, you can solve these. The challenge comes in being able to turn them. Not at all easy.
I picked these 3 and more up at IPP30 but all are available from Puzzle Master for around US$35. Dollar for puzzling value? I'd go for a megaminx. But if you want something pretty to add to your collection, well this fits the bill.
