lol, maybe I am a retard or maybe your phrasing sucks, I dunno. What I am getting out of your question is This one weighs X, how does yours vary from it? And I answered for you, it varies because it isn't the same saw. "How" being the word I am keyed in on. You want to know how it could be different than this one here you found on the interwebs. Notice how I didn't call you names or anything when I answered? Geeze, don't be so sensitive.
