I'm using an nvidia shield myself. it works very well. however, it's not $50. it's more like $180 without controller and $200 with. the controller works well, but there's no indicator on the controller itself if it's low on battery power, so I leave it plugged in while I'm using it using a very a long ps4 controller charging cable. there was an update a few months ago to make it compatible with ps5 and xbox series x controllers, but I haven't tried it.
