RE: Band saw or scroll saw
I'd say band saw. I've been building from plans since 1989 and only recently purchased a scroll saw, maybe I never took the time to learn how to use the scroll saw? I have a 5" throat metal cuting band saw that cuts everthing from steel to balsa wood with the same blade.
Shop Tools I use the most;
Drill press
Band saw
12" disc sander
9X19 metal lathe
Not so much;
Scroll Saw
Oscillating drum sander
It's niceto have them all however because each has it's own specific use
