Thanks to all that have provided me input into my inquiry. I have also considered the bulky air hose having to be drug around versus dragging around a 50 or 100 ft. drop chord (of the proper size of course).

Not having purchased any air tools yet other than a combination sand/soda blaster and already owning a number of small electric tools, including a 4" electric end grinder, I am likely to be getting at least an electric die grinder/cut-off tool to start our body work.
