Both the Miyoo Mini Plus and the PowKiddy X20 sell for $70 and run Linux at the entry tier, but they diverge in form and capability. The Mini Plus uses a SigmaStar SSD202D in a vertical shell and, running OnionOS or MinUI, reaches up to Nintendo DS emulation. The X20 is a horizontal device built around a RockChip RK3128 released in 2020, topping out at PlayStation 1. Choose the Mini Plus for broader emulation range; choose the X20 if a landscape layout suits your hands.
