I have an older pm2700 and a lot of the components look the same. One positive - 3 speeds as my PM2700 only has 2. Negative (to me) is the control box above the table vs below on the powermatic - when I want to make it a big router table by removing fence & power feeder I have nothing above the table top that might restrict movement of larger items - things like rounding over drawer edges post assembly would be a bit less convenient.
