8bitdo ultimate wired controller(make sure you get the steam deck one) regularly goes for $15. Works great with a dock.

Surprised at how well rdr 2 and cyberpunk 2077 look/run on the deck.

Max payne 3, titanfall 2, state of decay 2, batman arkham knight, vampire survivors, zero sievert(I had to kb&m it, maybe you could trackpad it better), metal gear revengeance, mgs 5, castlevania lords of shadows, middle earth shadow series, sunset overdrive(takes some shenanigans to get to work), yakuza 0, midnight fight express, risk of rain 2…
