I backed for the 3rd Batch of the One-Up, which will hopefully be delivered in Feb 2014. This will be my first/second 3D Printer as I am still waiting for the RigidBot (also from Kickstarter) to be delivered. If everything works to the schedule, the One-UP will arrive a bit earlier then the Rigidbot.
My greatest concerns are about German customs and their bad habits in destroying / sending back anything they are not acquainted with.
