My first scroll saw was a used Porter-Cable. The vibration was bad but I learned that I enjoyed scrolling. With what I know now, I suppose I could tune it to get rid of most of the vibration. But the killer was the non-liftable arm. To move the blade to a new hole meant releasing both the top and bottom blade clamps, move the blade, clamp both ends. I soon tired of that and bought my Pegas.
