Rapid Prototyping

Hi folks, this is my first post, my question is; what is the lowest price to print something,
say, something the size of a professional camera with lens, no inside parts, just an exterior,
lots of small poly's and surface's thought… so, what can I espect the price to be?
just a general figure, no need for any exact numbers here, the main question is; is it affordable?

By the way, I am a painter and sculptor, all art here, no working models or maquettes :)
just cool forms and shapes

Thx in advance
