Odin Lite is probably the one to get in terms of price/performance, still expensive though.
Since getting a GPD Win Max I haven't wanted any of the other handhelds though, total gamechanger for me. Being massively addicted to Valheim probably swayed that though.
GPD Win, GPD XD 64gb, PlayGo, RS-90, 3DS XL, DSi XL, GBA SP, GBBC Clone, Gameboy Pocket c/w screen mod, PSP Go
ASUS TUF, Medion Erazer, Toshiba Z20t, Dell Mini 9, Psion 5MX, Toshiba 3480ct
Tons of other old laptops and tablets.....
