With exception of the Mister, all consoles have either been modded or repaired. Bonus, everything is automated through Home Assistant so it will turn on the TV, switch inputs, and turn on the console, all via voiced controlled.
You can save a little money getting the adapter on alliexpress and the kit is $30 which puts the cost at a much more reasonable $47 per controller. The adapter also works with the NSO controller if they ever stay in stock.
