the PP3DP "UP!" 3D printer is considered to be by far the best quality hobbyist 3D printer on the market. The price recently dropped from nearly $3k to only $1500. this is the one that I am saving for. gives a good finish and 0.2mm layer resolution.

As far as scanners go, an xbox conect and some software off the net 'reconstruvtme' may be the way to go
