Find one used and be willing to tear it down and put it back together. Print extra parts once you have the process down. Prusa has kits if you’re willing to pay for a premium. Both assembled and built it all from parts.

Either way it’s a rollercoaster of an experience. Once you feel like you’re comfortable doing the first prints, you will look deeper into the abyss…
