What's better in terms of: Experimentation - I want to be able to tinker with my machine; i.e add an LCD or change the hot end Surface Finish - bare surface finish Tech Support - How bad is it if it breaks? Reliability - Can I depend on this? Dual Extruders - In the future?\ Build Volume Expansion - On either? Different Plastics - Laywood, PC, Taulman Nylon Other features - I heard Robo is getting Lights in their new Robo Anybody have experience with both? What are your thoughts?
