Normally I am a true lover of old woodworking tools, but when it comes to scrollsaws, the love kind of stops. Paul Hubbman can give you better advice on this then me, but the older scrollsaws relied heavily on cast iron and sheer weight to control the vibration. That only worked up to a point. The newer models of today use better balancing to achieve the same goal...that being less vibration. They do a 10 times better job at it too.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
