I recently went to Walmart and saw that they were selling the Nyko Switch Dock as the alternative for Nintendo own Dock. It’s half the price of Nintendo’s dock and it comes with an HDMI cable, the AC adapter, and a support piece that holds the switch at an angle in the dock. The Walmart I went to had 2 in stock. There is a link to brickseek down below along with the SKU.
