The current Excalibur saw is a re-engineered model that is made in China. People who have purchased it seem to be having issues with it.
The manufacturer who made the old Excalibur saws, now turns out Excalibur-type step children under different brands. There is the King brand, mostly sold in Canada, but the US Woodcraft stores sell it. Jet tools, now sells an Excalibur type, but it has some differences. Ray Seymore, of SeyCo, has his own version of the Excalibur type saw, also with differences. The one that seems to have bubbled up in quality, and seems to keep all the old Excalibur features, is the Pegas. It looks to be the current leader of the Excalibur type lines.
