I wasn't sure if it was ok to post items for sale here, but since other people have, here goes
I'm offering Pyraminx Stars for sale. The first one I made from an original Pyraminx and it has the white ABS plastic, and I'm selling it for $50 U.S., which includes free air mail shipping world-wide. I'll also be selling the new black pyraminx kind, also modified to be a pyraminx star for $40, including air mail shipping.
You can see my modifications at: http://cubeman.vg-network.com/unusual.html
I also sell glow in the dark, rubenking and shepherd's cubes for $20, $15, and $15 respectively. Again, price includes air mail shipping.
I can also offer Fisher Cubes for $80 including shipping.
