Personally i'd wait until they get a V3 update before deciding to buy them (Although there hasn't been any news suggesting they'll be out anytime soon :S)

Either way you can either buy them on Crypton's site but I don't think they ship to the West so your best bet is eBay, or as suggested above wait for their V3 update so they'll be up on the Vocaloid store.
