For a less expensive setup you may consider the Artisan hand piece with foot control, idle adjust without regulators. It is $774. This is the least expensive AirGraver setup but frankly, comparison-wise it is more versatile in power and speed than my competitor's top-end product. There is a three week trial time on the tools.
You will still need an air compressor, though. However, because the AirGravers do not require very much air volume, the smaller inexpensive compressors work fine. Ace hardware and Wal-Mart used to carry a $59 compressor as well as a $99 one. I'll see if I can find a link to them again.
Below is a chart from the AirGraver.com website. It shows the various impact speeds at different stroke adjustments of the Classic handpiece. The Artisan doesn't have this stroke adjustment but is fixed at the mid stroke length. Follow the "Medium Stroke" speeds on the chart to see the speed ranges for the Artisan. The tungsten piston also works in the Artisan and there is a column for that. Follow the meduim stroke column there too. For both the Artisan and the Classic the psi ranges are adjusted with the foot control or the PalmControl handle.
