Any news on this? I'm looking for the v2 platform and dual spitfire, upgrading from a v1 Duo. Any idea on cost?
Also, how well does it handle Ninjaflex filament? It doesn't look like there is a lot of support between the drive gear and the cold end of the extruder, which sounds like it could be a problem.
Edit: Ah, I just found the update on the Bukobot kickstarter page (which I wasn't part of) and just wanted to mention that I had not previously expressed an interest in the upgrade kit. I do see the estimated cost of $100 for single and $140 for dual.
