I’ve recently bought a Retroid Pocket 4 Pro (£120) and would highly recommend it. Emulates up to PS2 and Wii, and amazingly emulates many Switch games. Comes with Android so this open up the option for loads of native Android games with controller. This plays GameCube games well, has great battery life, great portability, WiFi and Bluetooth, halls effect joysticks, nice buttons and d-pad and is a great all-rounder. I neglected my Steam Deck for a couple of months after I got this. It cost £120 on eBay (you might be able to bargain down further if you’re patient and keep a look out). Prices are dropping because the Retroid Pocket 5 is out and is a huge upgrade (this is the console I would recommend if you’re looking for a stronger and more future proof option, but it costs about £200). If you’re looking to save a few bucks then you could go for the Retroid Pocket 4 (non-pro) or Retroid Pocket 3+…but I wouldn’t recommend those as worthwhile savings.
The other commenter is correct in saying your cheapest existing option will be your current phone with a controller.
Specify what “reasonably priced means”.
