Nice!

As Sramder mentioned, something like the rg556 (oled and the black levels make reading text against dark backgrounds much easier) or the Odin 2 (good quality ips and little bigger with a 6 inch screen). Other options would be something like the logitech g cloud (weak soc limiting systems, 7 inch screen).

Overall the rg556 is a great overall device with built in controls. Think the screen from an iPhone 14 turned landscape, about half an inch less wide and just a hair taller. Gives you a ballpark idea of size anyway. Hope that helps!

Awesome!
