help selecting a handheld console for makecode

I know its not exactly retro, hopefully the mods will give me a break.:D

I cant get my hands on one of the recommended consoles for the makecode web site for my son to mess with. All sold out or in the states

Does anyone here know of any of those retro units that amazon sell have a work around to use them? the retro consoles, they seem to be selling them with roms preinstalled, I've no interest in that as I've other solutions, but i'd like something where my son can play the little games he makes on makecode.com

I'm not linking in the amazon consoles, as they break the forum rules, however they seem to run a lot of emulators, so i was wondering if anyone know where i could get something will work for the makecode stuff along side the game emulators?

thank you

Any help is appreciated.
