If you like this poll be sure to also vote on the poll "quality 3d printers". The top two printers on that poll are the ulitmaker 2 and the ultimaker original plus https://www.massdrop.com/vote/quality-3d-printers-1
The Robo3D is a great printer with a great community around it. I have a Kickstarter backer (pre-retail) model and I've been wanting to upgrade to an R1 or R1 plus.
I didn't flag it but maybe take off the Form1 since it's a completely different class of printer than the rest of these?
