Help - Need to buy PixArt Sensor from WiiMote

Hi Folks
With the flood of WiiMote clones and the difficulty of spotting them.. I am hoping I can buy a PixArt sensor from one to the contributers here.

So far I have dismantled 5 WiiMotes from various sources (and several claiming to be Genuine) and all of them have a small daughter board. Not the PicAxe sensor in the various pictures that I have seen.

I am not sure if this is because I am in Australia and the models are different here or what.

So if anyone has a WiiMote (Working or Broken) that has the metal encased PixArt sensor and are willing to sell then please contact me viam a PM or here.

Many many thanks

Dave
