I have an older scroll saw from Proxxon, the DSH/E.
It is a machine that runs good and silent and I am very content with it.
The system to changes blades requires an hex wrench for the below screw, the one on top you can turn by hand.
My saw has variable speed and allthough I don't use it very often, I'm glad I have it.
The Proxxon DS 460 has a few changes, but not every change is an improvement.
You always need a tool to (un)thighten the screws from the bladeholders and I don't think that works fine when you do a lot of inner cuts.
Also the speed isn't variable anymore.
The only advantage from this machine compared to mine is the depth: 16" and 18".
In the Netherlands the saw costs about 385 Euro, that is about 535 US Dollar.
That isn't cheap, but here in the Netherlands you don't have as many choice as in America.
I don't know where Dennis lives, but that could be a problem.
As said I'm completely satisfied with the quality of my saw and I think the quality of the 460 will be fine as well.
But I don't know whether i'd buy this saw or not.
