I have tried several scroll saws and the hegner is hands down the best one, no vibration, smooth cuts, easy to change blades and travels well with easy, quick setup. I have the 22 inch and have had it for 15 year, I decided to try the Excalibur EX-21, I hate it so much vibration, what a waste of money. The RBI Hawk is another good one, but for me I am selling my excalibur and buying a new Hegner.
