I agree with mr alaskan, but the quality just isnt there.
Nothing beats a well made american made delta or similar saw. I think the saw stop kit can be adapted to most any saw.
Table saw is definately dangerous, but hand tools can be as well. Respect them all.
Saw stop is expensive. I figure a guy looking at older used saws isn't interested in that type of expense. I was surprised we didn't use one with out program - we were super safety oriented with the interns and crew.
One problem I find with many portable saws is lack of stability. Its not that they are unstable, but just not rock stable like you want -especially for accurate cuts.
