One thing, that is not often mentioned at scroll saw forums, is that there are many different uses for a scroll saw other than doing fretwork. I have played with making toys, compound cutting, bowl making, basket making, intarsia, segmentation, lettering and inlay. If one is doing just fretwork, easy blade changes is important and durability in cutting thicker (3/4"") wood not so much. When doing any of the other listed project types easy blade changes is not as important but durability is. This is why some people have cheaper saws that last for years and years others (like me) ware them out is less than two years. (I do not do fretwork)
