A typical setup starts at the low six-figure mark and can sometimes run as high as seven figures, according to Michael Hart, founder of SMARTT. The work of these artistic craftsmen has been seen in numerous hobby-related magazines as well as having been featured in Billionaire Train Fantasies, a show that ran on the Collector series produced by the Forbes.com Video Network.
"If you can dream it, we can build it," said Mr. Hart, while pointing out that they also build lifelike models of boats, aircraft, military dioramas, space equipment, and industrial structures.
