Sculpteo[1] and Shapeways[2] seem to be the two largest printers. According to what I have read[3], they are priced roughly in line with the costs of materials, plus some overhead.
You may just want to find a maker space somewhere near you[4] and go print it there. Plus then you get to play with their kit and meet some cool people.
