Hmm... Been collecting since I solved my first pyraminx back in the 3rd grade. I'm not big into sticker or shape variants like a lot of others but I can appreciate a unique variation now and then.
I also make several custom puzzles myself. If you're interested, just drop on over to my webpage, www.chrono.org and let's talk. I'm always willing to barter or trade when cold hard cash isn't the best option.
