I also agree with Kevin. I have the Excalibur and Seyco. The blade chucks spread apart on both of them from me over tightening the blade. Replaced the blade chucks on both saws with Pegas blade clamps a few years ago and no more problems. Good luck.
Lately Amazon has had the Dewalt for under $ 400.00 on and off. If you are not in a big hurry they will probably drop in that price range again. Usually only last two or three days on sale. I believe thats a pretty good price for that saw. Hope you find one soon and get started scrolling. Steve Good usually post the price drop on this saw.
