is electric better than air powered??? and why?
There could be good air powered ones out there, most people use electric because they don't have air, however. I'd say air powered ones are lighter, and are probably pretty flexible speed wise.
I stopped by a body shop and the guy was using an air powered one...go figure. One thing I'd seriously thing about is the stiff air hose coming out of the tool...I think I might be in favor of a more flexible electric cord which I could drape over my shoulder. The stiff hose might not be all that much of a problem, however. :nixweiss
If I were going for a rotary, I would probably get an electric one even if I would have air access some of the time, because there is usually electric access most everywhere. Electric power tools sound cool, too.
Something I haven't seen mentioned here are cheaper rotarys. They might sound bad while running; my friend got a knockoff sawsall [sp?]..."tool shop" brand from menards...he said it sounds really bad while running in comparison to "quality" tools.

It weighs less than 1/4 pound more than the 8 amp dewalt. This Chicago Electric one from HF is 11 amps...just for comparison. It is $49.99, and for someone who might not use it a lot, it might do just fine. Another thought for comparison: Mike Phillip's rotary which he wore a smooth, shiny spot on. Now there is a quality tool. That would be one reason to get a great machine.
I guess I can't help here a lot because I haven't even used a rotary myself, but I'm getting rotary cravings and am on the lookout for a good deal. I wish I had gotten the Chicago Electric rotary when it was on sale for half the price. Maybe they'd run the deal again for an Autopian group buy.

k, I'm done.
