Wisdens of Hastings in the UK. They have an ebay.co.uk store, super quick and easy to deal with. It's similar to a Z-Slash except more even balanced. Z is slightly head heavier and heavier in the hand. Has the same 'long shaft, smaller head' approach.
Wait I'm stupid >.< I don't even think there is one. I was thinking of the Mizuno TC700. Sorry for the error!
Well, it's not exactly a Z clone, so lets just say switching between the two is easy. Contact Wisdens yourself for shipping info. They shipped to me here affordably and efficiently so I can't see Canada being a problem.
