I got an xbox series, and wanted an extra controller. It seems there have been no stock on the standard $90 ones for ages and aren't expected for ages either.
There are some overseas scalper sites that might have them but I really want warranty.
There are heaps of wired 3rd party ones, and the $250 elite ones.
What's everyone doing for controllers?
Make do with the wired PowerA controllers. Microsoft sells it themselves, but they're sold everywhere including eBay and EB Games.
They feel hollow / lightweight and the triggers feel a bit cheaper, but they do work just like ordinary controllers.
