So, At Work we have a MakerBot Replicator, but i am looking for something more cheap, so far this are the two 3D printers i have my eye on:
-Solidoodle 4
-XYZprinting Da Vinci 2.0 Duo

I was told that the Solidoodle 4 has terrible support, and it needs way lot of fixing and fine tunning before you can use it correctly, it has a heated build platform, but it only uses ABS

The XYZ Dav Vinci 2.0 Due seems good, but it doesnt lokk like it has a heated Build platform, i was wondering perphaps if i could install one? (or it may have)

I dont exactly get the resolution thingy, so some help would be appreciated and i also was looking foward to buy a better extruder for whichever 3D printer i choose to build
I also have no problem opening one to change the extruder.
Thanks in advance
