It will take some tinkering to get working exelent, but you learn alot in the process, and you dont loose a lot if you loose interest in printing.

It prints great, but out of the box it is not so good. I have upgraded a few bits on mine.....not a beginner printer.
60.000 dollrs get you a printer that colors your prints at the same time. I do not reccomend this one for the beginner

There are Pro`s and Con`s with every printer. The perfect solution is not out there yet.
SLA printers are on the way. They use a bath of resin, and lasers or UV light to print/cure extremly fine layers/objects and make outstanding prints.
for 1000 dollars, you can get a good chiense one that mostly works.....but wait a little longer for better models
The 4 first printers mentioned all use 1.75mm plastic spools, for printing PLA, ABS, PTEG, or a whole lot more plastic stuff.....even rubber plasic, wood, carbon....all sorts of stuff.
