I have 3 printers, Wombot Modus 400x400x500mm build area, Wombot Exilis 250x250x330 build area and a Creatbot DX 300x250x300.
I have had problems with them all, but that is 3D printing.
There are heaps of review videos on YouTube I suggest you watch some of these and this should start you i the right direction.

Good luck.
