Query: Plastic in all the wrong places

I bought this stanley miter product to replace my Craftsman clamping miter, which I recently ran over with my car. Alas, Craftsman no longer sells this particular model anymore.The Stanley product is similar, only not nearly as heavy duty and has plastic parts at critical areas, such as the blade guides. (My old Craftsman was all-metal and endured lots of projects before it met its untimely demise at the hands of mr. goodyear...)Now, the blade guides can get torqued on with some significant forces. Bad idea to make these plastic. (I won't even mention the other plastic clamping parts.) In fact, the one I bought had these broken inside the sealed box. I suspect it was a return item . The blade guides simply won't last more than a few strokes, IMO. I will be returning this item. I'm willing to pay good $ for a good quality one, so I'll keep looking.Bottom line. Don't waste your time on this one.
