I bought a Miyoo Mini Plus three years ago and liked it so much that I wish I'd bought a more expensive model with analog sticks. Ended up putting far more time into it than my bulky old Steam Deck... until I recently took it out of my bag and found that the screen broke.

Sadly, while I finally have an excuse to upgrade to that more expensive model with analog sticks, it's not in my budget right now. So I got out my old DSi and 3DS and have been tinkering with softmodding. If you've got either of those lying around already, those are also very good options.
