Well not to a downer. but if where you i hald on the dewalt i have an Excalibur 21" scrollsaw its a good saw but with a few issues that are pretty common I'm finding out as of late.i only had the saw for little over to years and only use it for hobbie not for business and i had to replace several parts on it all ready including the motor cam and bearing.there still a knocking in the saw and found out the bearing and the arms for the blade clamps are worn as well.call the canadian office to get the price on the compleat blade clamp holder including the bearing there $115 each ip this way.i found a video on YouTube with someone showing some of the problems with it.its worth watching.heres a link to it hope it works.
