I can suggest the following, I had three advantage 2s before picking up my 360pro.

I modded all of the 2s with the following boards:

* https://github.com/kinx-project/kint - Great board, requires usb of course. Programmable with QMK.

* https://github.com/wizarddata/Blue-Wizard-Mod - Doesn't support QMK but does support ZMK but is bluetooth. Great board.

I picked the kint up on some pcbway type service, the blue wizard I got off ebay.
