I'm in the market to get away from the DJI Smart Controller and go to a standard controller, RC1A or the RC1B controller. Wondering if anyone has a tip to find a new one.  Been poking around Google and can't find any. There is the Rotorlogic but there are too many bad reviews on that unit, so looking for a genuine DJI standard controller for my Mavic 2 Pro.  
Any ideas where I might get one of these?

Ebay, and try to get the RC1A, the RC1B does not create DAT flight logs.

I've seen a few on facebook marketplace recently.

Is there a label identifier that shows if the unit is A or B?

At the top of the label on the back of the controller.
