It has to do with precision. Lower cost machines with have lower
tolerances. This may or not matter depending on the use of your drill
press. Basically, you test for run out by chucking a piece of stiff
wire (such as a coat hanger piece) and bending the wire so that it
barely touches a large circle path on the table top. When the chuck
is turned, the gap should be the same all the way around if there is
no run-out. Personally, I'd shop for a high precision machine with
the fewest gadgets to get a good value.
