Seeking 2nd hand Wii ‘Exerbeat’ or ‘Walk to the beat’ games

Description:

Hi am looking high & low for either Exerbeat or Walk to the beat games from wii, they are both exercise games & I cannot locate them anywhere. If anyone has any they don’t need I would gladly buy them for about 15/20 pounds. I used to live in Crystal Palace & Bethnal Green in London but am now stuck back in Australia :( Thanks a lot.
