Will Seyco does have some history, they sold Excaliburs for years, are experts with them. The Seyco saw is an Excalibur with other features they feel customers wanted based on their years of experience. Most important, their long earned reputation of customer service and fair dealing.

I have watched this saw, been on the market for over almoset 2 months, scroll saws do not sell in the North West. It is missing the part for attaching the dust vac by the bottom clamp and it appears to be missing the flexible end portion of the dust blower at the top clamp. Easy to replace parts. Maybe offer him $500 see what happens. It is 19 years old, however Hegners are the same now as then. There is a nice Excalibur in the Portland area, they want to much for it in my opinion but it may be negotiable. Just saying there are high end used saws in the NW. Lots of Hawks. May have to travel a little but road trips are fun.
