A good deal - Those are a surprisingly useful tool.
I have one of the larger versions of it, with the "heavy duty" hand piece that takes collets, and a cast iron foot pedal.
Bought it a few years ago, from a guy for $40 - I don't know how I ever got along without it.

DD series was discontinued a long time ago, so you'd want to look into availability of parts
