Due to the HAZ (Heat Affected Zone) and reflective nature of SS, you 
might want to also look at AWJ (Abrasive Water Jet), which is slower and 
generates a wider kerf, but has zero HAZ and doesn't care about 
reflectivity.  Usually, AWJ cut parts are stacked MANY deep since AWJ is 
more efficient as the parts get thicker.

Another option is plasma cutting, often cheaper than laser, it has a 
wider kerf than laser, but is a cheap system to maintain and run. Keith 
Fenner on YouTube has some pretty impressive demos of cutting sheet 
goods at high speed.
