What printer around 600€

[curious aardvark]

for $600 you'll struggle to find anything better than the qidi: https://www.amazon.com/TECHNOLOGY-3D...&keywords=qidi

Not the largest build volume - but I've rarely needed anything bigger.

And if you're serious about 3d printing - Printbite makes life an awful lot easier :-)

Both geetech and xyz are kind of low end in build quality and support.

qidi are at the opposite end.

The other thing I'd suggest is change tact completely and go for a big arse delta. : http://www.reprapmall.com/index.php?...product_id=117

yes it's a kit, but very easy to build and stupidly large build volume and very fast print speed.
Completely opensource, quality components and great support.
My build 'blog' for it's smaller sibling. http://3dprintboard.com/showthread.p...t-a-delta-kit-)
