Was looking into the electric orbital sanders out there and came across these to, porter cable 390k and the dewalt D26456. These two look and sound the same but different brands. Was wondering if anyone has used these sanders and what they thought of them? Also what is a good amperage for an electric orb? I am only used to air orbs and am trying to get a feel for what there is to offer in electric for at home. I like the look and idea of the two sanders because I think the general shape of them will be an easy transition from air to electric instead of the typically taller electrics. Any knowledge on the subject would be great.
