Buy the Prusa Core One.

Orange 4K V2 owner, r/resinprintingFine budget printer. Not as well-supported as Elegoo, but it gets the job done.
Orange 4K V2 owner, r/PrintedMinisFinally, Prusa takes on Bambu! The Core One is better in a box.
Prusa Core One owner, Tom's HardwareRail smoothness holds up well after months of hard use, minimal belt wear, and consistent chamber heat stability.
Prusa Core One owner, Prusa ForumIf you value open source and lifetime support, Prusa is still the gold standard. Just bring your wallet.
