Back when I was role-playing this would have been something I would have killed for, though perhaps back then I would have baulked at the cost ($30 for a realistically paintable model, upto $99.99 for a bronze). It is, however, a really good tool to make a character portrait for free. If you have a really good home 3D printer (and having seen minis printed from home-3D-Printers, it really does need to be good to match cast models, the layer-lines are very visible when you're used to Games Workshop grade models...the best resoution these guys offer is 50 micron layers) you can download the STL files for a fairly nominal fee. There are a huge number of options to play with, especially around pose and scale.
I had a bit of play doing 2 of my favourite characters from very different settings. Lucas Newell was my ICAR character, and Bollax was a long-running AD&D 2nd Ed Dwarf Warrior/Priest (he had a much longer name and title listing his conquests, as modesty was his dump stat). In both cases I was really impressed at how quickly I could get very close to my mental image of both characters. The colour printing options look a little basic (though it might be possible to add some washes to bring some more depth, or dip the models...though given the cost that might be a high-risk strategy).
