I've been toying with the idea of getting one myself for a while now. Over 20yr experience in 3D computer modelling I've got a ton of models that I'd love to have sitting on my shelf.
Then I'd have to get a 3D laser scanner to complement it...
I'm still waiting for the affordable 3D printers to be capable of high quality fabrication of high load parts (such as replacing damaged gears in a high torque RC monster truck). Knobs and dials don't tend to wear out much be being able to replace things that break with a replicated version that is as strong (or stronger) than the original part will be awesome. I don't think we're too far off though and for now I'm jealous of your new (toy) tool!
