I researched for a long time before buying my Original Prusa i3 MK2. I read and witnessed so many people who wanted to buy knockoffs just to save a couple hundred dollars…most all ended with regrets and none stop print issues. The Originals prusa i3 MK2 (now MK2s) is rated as The Best 3D Printer for 2017 which remains undisputed. The support you receive from Prusa is unsurpassed and the support forums are amazing. Basically, you start with a perfect printer of unmatched quality once it is built then you begin to learn knowing if there are print problems, it is NOT your printer printer, it is your lack of knowledge which quickly changes as you print and ask questions. Shortly after, you have amazing prints with the widest support for different filaments. when a printer lacks that level of quality, you can learn everything there is to learn but that printer will never print as good as a printer such as the Original Prusa i3 MK2s. Buy the kit which saves you $200 (currently $699). The build instructions are incredible; you cannot make a mistake. The advantage of buy the kit and saving $200 is you’ll know how to disassemble the printer for future upgrades or repairs. You cannot go wrong in buying the Original Prusa i3 MK2s. These printers are amazing! I hope this helps in your quest of buying the right printer.
