12 inch Bunnicycle

me and my 2 other friends all want to get 12 inch wheeled unicycles but the one one unicycle.com people say would break if we jump with it so but the bunnicycle seems really good (http://www.kahero.com/boutique/fiche_produit.cfm?ref=MIK12&type=87&code_lg=lg_fr&num=1&pay=0) for a 12 inch, so I was wondering if anyone knew of an american site that sells bunnicycles.
