Need expertise before buying a first low cost 3d printer

one thing to bear in mind is that you are buying direct from a chinese bargain basement shop.
So don't expect any backup. ie: if it goes wrong make sure you'll be happy fixing it yourself.

Don't underestimate the fact that you WILL need support from the company who sold you the machine at some point.
