I started out with a Makerbot Cupcake, then purchased a Cubex. I was tired of constently rebuilding the extruder on the cupcake so thought the Cubex would just work. Unfortunately did so before people had actually received their orders so most reviews I read were not really reviews. So after a few years of issues (I'll Filament Feed you, lol) with that I recently picked up a Wanhao.
