That's a pretty darned pricey printer even with the slightly larger than average build envelope.

What software is it running? what slicing software? The site says shipping only to NZ, will you be offering shipping to other countries?
Are these open sourced or closed source software?

I am a 3d printer enthusiast and currently own 2 printers (and building a 3rd) and the first I paid under $1500 shipped and it's Dual-extrusion capable.
Just offering up my experience in buying and operating 3d printers....I've made a bad buying decision when I first got into my own 3d printing hardware.
