I have recently bought a `Miyoo Mini Plus` for about £70 (inc taxes) and it is able to run most old console games up to PS1 just fine and the build quality is good too.

It is linux based and community has made an alternate OS/UI https://github.com/OnionUI/Onion with custom scripts, webserver and support of many other systems etc.

I couldn't find the price for Analogue, but it will probably be too expensive in comparison.
