Zune 80 in UK?

Hello,

A few months ago i bought a Zune 80 in the UK. It all works fine however i am going on holiday next week and require a wall charger for it, however I want it cheap! I am buying off amazon UK and would like links to which one i can buy? I have found ones that do the Zune 30 but say in the description that they are unsuitable for the Zune 80 but I do not believe this to be true. the next best thing would have to be a USB wall charger, would this work?

Cheers in advance.
