John gives you some good advice and i would definitely check out which model it is.
but a few years ago, i was looking at a dewalt planer that was a display on clearance, i was scared some parts may be missing. i called dewalt and asked them for their opinion. they asked what the price the salesman had given me. i told him, he said hell yes, take it!!! if anything is missing we will send it to you free of charge.
you might call porter cable and ask? they may do the same.
light travels faster than sound, this is why some people seem bright til you hear them speak.
