I’d actually recommend the opposite. Unless you’re a DIY hobbyist who loves taking everything apart and you don’t want to print immediately upon receiving it, it’s worth it to buy the prebuilt Prusa. There are so many many steps in assembling a MK4S that there are that many steps to get something wrong. Better pay a few hundred extra to get one that has been assembled by a more experienced person. And I say that as a makerspace coordinator who works with a lot of 3D printers.
Assembly teaches you how incredibly complicated the assembly is. I’ve adjusted pre-assembled printers with minor inconvenience. But the first one you put together can take more than the estimated 6-8 hours.
I guess this is the disconnect. I’ve assembled one, but I don’t feel like assembling one necessarily conveys this. The instructions just tell you which part to attach to which other part. It doesn’t explain why much of it is important or how it functions.
The other difference is that I haven’t upgraded any. I have some MK3S+ printers that I are likely to remain that way since the upgrades are so expensive and the process so laborious.
For personal use, I’m waiting on the CORE One from Printed Solid but it’s only available for education, government, etc at the moment.
