I'm looking for a cheap tank mouse that has the daughterboard PCB with the membrane-style buttons like this:

I don't care about the condition of the rest of the mouse, the more broken the better so I don't feel bad cannibalising it. It's only the button board I'm interested in, that's the only bit that needs to work.
Ideally UK-based as it's not worth paying for expensive postage. I don't want to pay more than £10 all in for this otherwise I'd just buy a tank mouse off the other bay.
Thanks
