My semi-professional opinion (lots of experience with hobbyist stuff) would probably be the original Prusa i3 (
http://shop.prusa3d.com/en/3d-printe...3-mk2-kit.html) if you're ok with paying a bit more. If not, the Makerfarm i3 printers can be upgraded for auto level, but if you want something that isn't a kit and works out of the box, the Printrbot would be good.
