I've never used an Eastwood one so I cannot compare but I will tell you this it's like a drum sander when you cut down a hardwood floor it's not going to give a perfect pass unless you press down hard and you're not going to be able to do that all the time and that will Mark the metal and cause Heat so mine had eight layers and I think I could have did a lot better with the DA.. it's eats one layer effortless
