Also have alook at the flsun cube: https://www.amazon.com/Leveling-Cube...sun+3d+printer

I'd go for one of these over an i3 any day of the week.
Any setup where the print head does all the x&y movement will be that bit more precise and faster than one where the bed moves around as well as the head. I reckon ;-)
A full cube frame gives better all round stability.

It's a good machine - no idea why people go for the i3 setup more than this kind.

Me I'm different again - full on delta convert - but would recommend that as a second machine rather than a first :-)
Cartesian setup's are just easier to start with.
