I had one done of my RobbyBobby character a year or so ago.  It cost me $65 to do and the quality was less than satisfactory.  It was done on what is billed as a 3D printer from an OBJ file that I provided and, among other things, it couldn't do hair at all because of the transmapping.  It also couldn't do the clothing because that was only two dimensional.  The bottom line is that I ended up with a bald and naked version of myself in my twenties that is a bit...shall we say..grainy.  It has been a bit of a conversation piece, though.  We keep it in a curio cabinet along with the mythological statues (Pegasus and Perseus, Poseidon and Hades with Cerberus).

Oh yeah, it also provided a stand in the object file that didn't make it to the final piece.  As a result, there is a little strip of "material" connected to the feet, but it's not enough to stand the piece up.  So, I glued a couple of magnets to the bottom and put it on a metal coaster (the coaster is pewter, so it kind of looks OK like that). :D
