tuttminx

Even though some said that these puzzles are hard to find, I have some what found both of them in different shops. Should I get the speed tuttminx or the rayminx? Speed tuttminx: Price: $53 (assembled including shipping) Rayminx: Price: $111 (assembled and stickered including shipping)

Okay you guys, I've got a tuttminx yesterday, and it's hella fun. But I'm kinda stuck with the last layer; I've tried a couple of things, but since the hexfaces have turning-restrictions, I can't figure out how to solve the last layer. Does anyone have a tutorial/vid/algs for the tuttminx?
