I was curious about this, so I looked up some weights on the manufacturers' websites to see for myself. There were three corded polishers mentioned in that buyer's guide Tcoat posted:
Porter Cable 7424XP - 5-1/2 lbs
Meguiar’s G110v2 - 5.5 lbs.
Griot’s Garage - 7.73 lbs.
Here are three cordless polishers:
M18 FUEL™ 7” Variable Speed Polisher - 6.4 lbs w/ 5.0 Battery
Ryobi 18V ONE+™ ORBITAL BUFFER - 4.2 lbs (not indicated whether that's with or without battery)
Makita 18V Cordless 5" Random Orbit Sander - 3.6 lbs (with battery)
So whether it's corded or cordless doesn't seem to be the determining factor in the weight. Although I haven't used any of these myself, I have used grinders quite a bit in my welding, and it seems to me the ergonomics would be similar. With that in mind, NONE of those corded buffers look comfortable at all. They're too heavy and don't seem to be shaped correctly to use one-handed, but there doesn't seem to be any thought at all in the design of the case for the second hand. We had a big 7" grinder at the shop that was designed that way, and despite it being the most powerful grinder we had, nobody would use it because of how unwieldy it was.
Maybe you guys who use them regularly see something else I don't, but from what I'm seeing online the only disadvantage I see in cordless is that the Milwaukee only goes up to 2200 RPM. The two cheap cordless ones both go higher, though, and still seem like they'd be easier to handle than the corded ones.
