The Chocabyte 3D printer is probably the cheapest chocolate printer out there. Having said this, it still is in a pre-order phase. I am not entirely sure when it will begin shipping. They are in a process creating a library of templates which will help users jumpstart their own designs. I am not sure how accurate or how much resolution the prints will have, but the price I think is $99(might want to double check that) More details: http://www.solididea.com/
