It that is as little used as it looks, that is a great buy.
If you look at saws often, as I do, It would appear, at least to me, that DeWalts have the best re-sale value of any scroll saw. I see them for sale a lot and it is usually from $300 to $400 area. New you can get them pretty consistently if you look around, for <$500. That is a 60% re-sale. Take the higher end saws, I see Hegners often for <$600. that is around a 30% re-sale and same for Hawk saws. The best used Hegner I have seen recently for sale is asking $680, and I would buy, and travel the 300 miles to pick it up, it if I had the extra cash. New it sales for $1695 that is a 40% re-sale... This is the west coast, may be different back east.
