Random Orbit Electric Sander vs. Pneumatic DA Sander

[blacter]

I already have a Porter Cable random orbit electric sander (Model 7335) that I use for polishing my Bug. Can you guys tell me if that's equivalent to a moderately priced DA pneumatic sander or are there reasons to prefer one over the other.

You will find that a pneumatic/air DA has more speed control due to the air valve/trigger control... you can set them real slow to real fast depending on the type of sanding your doing/media your using.

the "vibration" that a DA offers will help you immensely with feathering.
BTW, the "Snap On" DA which a few years ago cost about 4 times the amount of a "regular" DA is the shitbombdiggity!
