For less than $2,000, you could get your hands on this nifty Radarcarve Model 2 from eBay. This machine basically “traces the contours of your guitar, using those measurements to carve up the block of wood so it’s exactly like what you currently have.” Auction page.

Of course, you can use this to duplicate any number of things other than guitars as long as they fit and are made of wood. Wooden pants.
