Bluetooth Trackball Does Anyone Have A Bluetooth Keyboard With Trackball?

Does anyone have a Bluetooth keyboard with trackball? - bluetooth trackball

I studied dozens of shops and number of sites, but I was only two devices that can meet the criteria. One for $ 150 and another for more than $ 300! That's crazy.

Standard RF and RE are unquestionable. Does the Bluetooth trackball.

Has anyone a keyboard like that? Any suggestion that we can find?

Thank you.
