Shop Smith 20" scroll saw

[Frumper64]

There's a 20" Shop Smith saw available at a very good price, but I don't recall ever hearing anything about their scroll saws. Does anyone have any experience with them? I know Shop Smith tends to make some very nice machinery, but that does not necessarily mean they make a good scroll saw. This is the one that is a stand-alone (not the version that mounts to a Shop Smith and uses that for a power head).

Thanks for any inputs,
Jim
