I've got a Logitech wireless controller for my PS2 - the plate on the back is labelled 'Cordless Action Controller'. Part# 863239-0000

While tooling around in Katamari Damacy a few minutes ago, the left thumbstick broke. It looks to me like the bottom of the knob is plastic, and is attached to a small metal shaft underneath, and that the plastic around the metal shaft just broke.

The result is that the knob just flops around limply, and isn't actually attached to the metal shaft, and therefore doesn't control anything.

Do any of you possibly have a broken controller like this, that I could use to get a replacement knob?

Thanks
