I like the Flexion extruder, but I can't justify the costs. The rear mounted blower concept and extruder enclosure window is really interesting to me. I love the idea of not having all that crud in the way. And being able to see it work would be way awesome too. Do the two lights/buttons(?) inside have something to do with the out of filament sensors? The filament reel holder looks intriguing too.
Really cool! I took the plunge on the dual extruder. I may also build some of the other stuff over time.
