Larry from what I have been reading the ex has an adjustment so you can also true the blade front to back as well as side to side. The DeWalt doesn't have that option. I saw a review on youtube where they stood a nickel on it's side and turned the saw on and the nickel didn't move. With the saw I have now I can't even do that with the nickel laying flat. Not sure if I'm going to get a new saw, just doing some research in case I do.
