I haven't yet started really designing my own prints beyond basic shapes and such, but I would definitely recommend the Ender 3 Pro that goes on sale at Microcenter for $99 for the folks here asking about getting started. Manual bed leveling is tedious, but other than that it's fairly plug and play.
I'm brand new to 3D printing and have already printed loads of useful stuff with mine. I like switching colors, so I've already spent more in filament than I paid for the stupid printer - that's how they getcha! Just like printers and ink - what they lose on the hardware they will make back tenfold on the printing materials.
