Well, there's always the German website
shopping-guru.de. They sell sets of 6 dice for 8.20 Euros each, which, while cheaper than the Shapeways customs, are still heck of expensive for just dice.
You could also do what I did and just print properly-sized labels onto sticky paper, cut them up and paste them to otherwise-normal d6es, which cost much less per each than specialty stuff. I make no claim as to these dice being properly weighted to roll even odds after sticking them up or anything, but I didn't notice anything untoward during my playthrough of slev's HQR 4 years ago, so it's probably fine. Behold through the magic of blurry phone-camera pictures!
