I saw this thread start last year and it got me wanting my own C3PO, so I purchased the files from Do3D also. I think the price is fair for what you get. I wouldn't have spent any more than what they quoted though. I have been mostly satisfied with the models so far. My biggest issue has been with the lines on the chest as has already been pointed out in this thread. The pectorals and collar bone lines seem way to sharp to me. I asked the Do3D guys if they could change these lines to be smoother and sent some reference photos to show how much different they looked. They responded within about a day and said that different reference photos show the lines on the chest sharper and they referenced those photos. I guess that is fair, even if I disagree. For me, this was too different to ignore so I used Meshmixer to smooth the lines to my preference. While I was at it, I also increased the angle of the underside of the pec's so they look more "lifted" and I rounded out the pointed areas in the center where the collar bone meets the pec's.
