Randy, I bought the Chicago Electric with sliding tray (not the bridge saw you have pictured) and am still using it today. My brother and I have laid down several thousand square feet (lost count a long time ago) using that junker saw, and it has served well. In my opinion, you're not going to break that saw, but you probably will wear out the blade in no time. I haven't cut slate before, so maybe the blade will be fine.
regards,
