This is one of most stable printer in the market, prints consistently good, easy to learn and based on repraps.
I personally started of by making own reprap (prusa i3). I got its parts printed from an another reprap 3D printer and assembled it. It was a huge effort though to calibrate it and start making good prints. Took me 2 months, but this whole understanding inspired me to create my own 3Dprinting service company Solidry later.
