Cheap Printer for Beginner

I think this would be your very first 3d printer because it's really cheap

You can learn how 3d printing works and you can print an upgrade to make this printer better and better

You can make a clone too with when you know how it works

Prusa i3 Mk3

New to 3d printing, bought one from Amazon supposed to be all friendly, easy to use etc etc but had nothing but problems so took the plunge and bought a Prusa i3 Mk3 and so far have been extremely delighted with it, took my time building it over a week, then setting up, had a few problems but think I have over come them and now starting to slowly test my printing out, made the tree frog that came with it, bulldog and Prusa logo, all good so far, now for some thing bigger, just have to wait and see how it goes but looking good so far..........................

Easy to use

I like the "skeletal" look of this printer. This makes it easy to replace various parts.

Amazed and Dazed.

Easy to assemble and get first print going.  Really appreciate the quality of components. First "real" print after a few calibration cubes (and online research for correcting setup issues) was a filament guide/holder.  Took a couple of tries, but finally figured out that my drafty garage workbench was not the right place to set the printer up.  Lots of little improvements (tweaks) are available via the internet and every one implemented so far has made this printer a little better.  I fully expect that as I gain experience and knowledge this printer will continue to impress me with its capabilities and value.  Very satisfied.
