I'm trying to find a place where I can purchase this:
http://reprap.org/wiki/Metal_Gear_System_Extruder here in the US. I've only been able to find it here:
http://www.reprapsource.com/shop/shop/show/6770, but as it's shipping from EU the shipping is more than the parts itself. Does anyone know where I can buy these in the US? Thanks!
