Hmmmmm... hawing advised my own brother to buy a Bambu about two months ago, i am in a pickle as i still have not told him to cancel it nor did i ask if he did buy it, so i need to make a call.
For now the only viable options remain, depending on budget, Creality stuff, preferably CR versions but they do tend to get in the Prusa price range or more, Prusa, and Creality K1 or K2 or whatever is the latest version of it with multicolor option.
Enders are OK now that Bambu is out, as A1 mini killed them in a single swoop, but resurrection happened!

Prusa are a bit pricey, still, but good quality and open source everything
Creality CR versions are much better, had about 11 of those (3X CR10MAX, 2XCR5Pro, CR30, CR6 two color, CR10S V2, some others and Ender 5 Plus, the only issues ever was Ender 5 clogging several times till i changed the hotend, then modified it and made rally fast and abused the poor thing for several years without a hiccup) but they were quite hefty priced, no idea what the situation is now, and the only one still with me is a CR5PRO modified for high temps and klipperised, in use for several years and had a broken motor cable on it once.
-
-200$ Ender
-500$ Prusa or K1
>500$ K2 with or without multicolor
And do double check the K1/K2 situation as i am not sure if the new one was K2 or K1 plus or whatever they decide to call them, not very good at naming things those at Creality.

Of the CR variety, try finding a used CR10S V2 with BL-Touch, not with an inductive sensor, never had a failed print on it, ever, although slow, but it can continue prints on power failure with it's original firmware. If you can find it for 200$, it beats the living s#it out of Enders, and does 300x300x400mm so not small.
CR 5 Pro is also good, but only modified to direct drive and while at it change the hot end to high temp one, put a lid above it and print ABS/HIPS, i would gladly pay 250$ for a well cared one. Be aware that printing PLA with the open door is a must, even PETG, and as is will not be good for ABS/HIPS.
Also be aware that CR 5 PRO is a 32.5KG beast, so not easy to move by one person, at all, i know i moved it several times!
