Trying to understand the usage and different purposes of the "table widener" - 493139 for $97 and the "extension table" - 488756 for $33.50. They both offer an offset base. The cheap version has the handle/knob with a thin plate and the expensive one has the rotating chip catcher/deflector with a thicker base. Is there any reason to have both? Seems both are for edge trimming operations. Thanks.
