Personal Transponder - Brushless ESC

[Karting]

I need a personal transponder, not bothered about condition aslong as it works

Also need a brushless - Sensorless esc which is capable of running a 1/10th 9t motor, once again not bothered about condition and looks aslong as it works.

£? - Cheap as possible, also not looking for top end stuff
