Original Prusa i3 MK3S+ Review
But if you don't mind paying for proven excellence, the Original Prusa i3 MK3S+ easily earns our Editors' Choice honors and is as good as consumer-grade 3D printing gets..The Original Prusa i3 MK3S+, the latest iteration of Prusa Research's flagship 3D printer, adds sturdier parts and an improved print-bed leveling system to an already fine-tuned machine

Wife just said "Get yourself a 3D printer for Christmas", I'm so excited, watching YouTube videos but I know nothing.
The Prusa i3 MK3S+ is kind of the gold standard workhorse printer. It's not the cheapest, but they're very reliable.

Is a prusa mk3 worrh its high price?
It is now a reliable, albeit rather limited, printer. The entire process has been fun, and sometimes frustrating, and is far from complete, but this is time that I could have spent doing other things. If I was starting again, I would buy either a Prusa MINI+ or a Prusa i3 MK3S+.
Never owned a printer, never used one but I think it's super cool and I'm a quick learner. I've been eyeing the creality 3 (newest model) but came across prusa while researching and on a total impulse pulled the trigger on a Original Prusa i3 MK3S+ kit.

$800: Prusa i3 MK3S+, Qidi-x Plus. Another disclaimer is that on this subreddit, people will often recommend the Ender 3 as a printer. I highly advise against this, because it's a common trap. The Ender 3's components are especially poor compared to printers around its price range or even cheaper and will fail very often.

It is because I can trust it to not generate faulty gcode for my printer. My printer is a FYSETC Prusa i3 MK3S replica and i use PrusaSlicer and non-modified Marlin firmware from Prusa as well.
Upgraded to the I3Mk3S+ and I'll never go back. Goodbye ender 5 modded to the max.
my Prusa mk3s+ is the 3rd printer I've owned (Technically 4th because I got the elegoo saturn, but its a different manufacturing process so I don't count it). It was also my first kit printer. Its by far the best printing experience I have had. Quality of parts is perfect, Noise levels are lower, it saved one of my prints when it detected my filament had jammed on itself on the spool.

Day 3 of owning a Prusa Mini+. I learned a lot from my Ender 3 V2 but this is a whole different experience! Tempted to sell my Ender for a 2nd Mini, or towards an i3 MK3S+.
For single color prints the i3 MKS3+ is far preferred over the Makerbot Method. I get more materials, the software is better, and it's faster and quieter (when set on a paving stone on top of foam). For prints with supports - it's a wash - it's a lot slower using the MMU to switch between PLA and PVA, but the slicer does a better job and the fact that you can use a combination of PVA/BVOH with PLA for supports is amazing (because PLA is _way_ cheaper).

Really want to get the MKS3+ maybe even mmu2. Would be first printer. Is it worth waiting for the next Prusa product?
I would say go ahead and just get the Mk3s+. Prusa has been good about providing an upgrade path for the new version of the printer without having to buy a completely new on. As far as the mmu from everything I heard it’s better to get really good an comfortable with just the base printer first since it can add a lot more trouble shooting to get it working well.

Never buying creality again - Prusa mini+ my best option?
The MK3S is an outstanding printer. You can pay more and buy it assembled.
