I am a big geek, and pretty new to 3d printing
The Monoprice I have actually belongs to my brother, but I started printing a few things on that. My very first printing was on a Makerbot at the library years ago, but the first that I had to maintain and really learn was my brother's Monoprice Mini that I borrowed, and since then I have been buying and fixing used printers for myself and to then sell off to others in need of cheap printers.
