We purchased this Monoprice 3D printer ($300) for my kid's project and it definitely serves as a family printer for casual use. So far we have printed a motor mount, a computer fan shield, a dice box, two rudders and a EDF.
Of course it has glitches here and there. The biggest complain I have is it has to be calibered very well to have a clean print, and for an ordinary job, it takes a LONG time to print, ie. that computer shield took us 3 hours.
But that's all minor issues.
