Wanhao Duplicator i3 V2.1
The Wanhao Duplicator i3 V2.1 is a great 3D Printer that has an excellent community and customer support. I have had great trouble finding a good, reliable 3d printer for a while when I found this one. This printer is a bit difficult to get out of the box, but then it is only a few screws before you can start printing. The print quality is very good (I used Cura as my slicer for this, other slicers may have varied results), but things can get unpleasant if you try to print too fast.
My print bed was bowed, but the Wanhao website (if ordered from there) offers free parts replacement for a year. I have let them know and they have shipped a new bed to replace the current one with only a few emails.
One thing to note is that it is not easy to print flexible materials. I had to print an upgrade from thingiverse, and now I am able to use flexible filaments. This printer is very upgrade-able, and chances are that if you have a problem, someone made something to fix it.
