i am Community Manager for Makible Ltd in HK and we're developing the Makibox A6 Desktop 3d Printer, a $ 200 (without heatbed) solution.
We're in the last development stage before we ship out the Beta Boxes (hopefully next week) and then we will have to work through the Backlog, before we can send out the newer orders.
You can follow our progress from Funding Phase to Design Iterations on
makibox.com
We also developed a Pellet Drive Filament Extruder, the Ramen, which can be used to turn Pellets (much cheaper than filament) into printable filament.
If you're interested in "affordable" 3d Printers, i highly recommend to follow Billy Zelsnacks Post (he produces the Printxel 3d Printer) about FDM Printers on the market:
Feel free to mail me directly, if you have any questions about the Makibox or 3d Printing in General.
Kind Regards
Nils Hitze
