Just get something good cheap ones are not a good deal. They are known to have many problemsyo, so I'm gonna get an Nvidia shield controller but I'm not sure what Bluetooth version I need if it even matters, if I just get a Bluetooth 5.0 wifi card will that be fine?
Do you have a PCI e connecter for it?How do you define "cheap" I just found an MSI one for $80 AUD
