I have a Sanwa M11 2.4 which has been used twice. It still has the protective film on the screen. It comes with Re-chargable cells LRP2700s and the controller works.
I am selling it as I prefered my other controller
but hopefully you will have fun enjoying it.
Its going for £180 and I do take paypal. Postage we will have to arrange over pm
Cheers
Trish
