I had a Dewalt713 that had a catastrophic blade failure (Dewalt blade) last month that literally caused major damage to the fence and table. I am lucky I did not get hurt and after one email with pics to Dewalt, they requested I send them the saw at their cost and offed a DW716XPS as a free replacement. I took it. The quality sucks compared to my five year old 713. The table is much thinner and has been downsized to save money. The motor looks OK, but the brushes are not going to last long- they went cheap. As for the plastic, it too is thinner and cheaper. As for being square, not a chance in hell! It needed a lot of adjustment! I am not impressed and it seems the miter saw line is not what it used to be, unlike their table saw line that is getting better and better.
i just got my Feb/March issue of Fine Homebuilding and they did a comparison of 12" non-sliders, specifically the Dewalt, Bosch, Craftsman, Rigid, Makita and Hitachi. It's worth a read if your box store has it or Barnes & Nobles has it. It goes over everything, including features, max angles and capacities. Bosch won for a variety of reasons.
I think I am going to dump this and go with the Bosch.
