Well, it's just like the one I bought and sold only because it was too big. I see the two small holes on the upper are so it uses the latest clamps. It has the front tension release. Without looking under it to see what motor it has, I don't think it has the Fasco motor that was the one that had some problems. Not sure how many but they got a bad reputation from somewhere. The other thing to look at is at the rear of the saw where the V-groove is and the small V cam fits into the notch. It appears to be a great saw. I bought mine, with 20 hours on it, for $250 but I live in an area where used stuff is abundant. I could never give the asking price for anything unless I really wanted it and just HAD to have it. If you REALLY want it, offer $400 and see what happens. Me, I'd probably start at around $300, but that's just me. Check it out. It appears to be a nice saw. Also, be sure to get as much of the stuff that came with it as possible. The manual, and all the blade clamps and anything else that comes to mind. It seems like some or most of these saws came with a foot switch and some had mag/lights.
After taking another look at it, the little V-cam and V-notch look really good and sharp.
