Thanks for the info . Click on this site ,they have the 7424 and the 7424XP for $109. Thats the best price I could find. http://www.tools-plus.com/porter-cable-7424xp.html. Thats new not refurbished .
To answer your question. The XP is an improved version of the 7424. It is supposed to have more power and cut down on the vibration. The initial reviews on it are very good.
