I purchased this saw...
Customer Rating: 




and, hands down, it is one of the best tool purchases I have ever made. I cut through two thicknesses of treated two by twelves (glued together) for an arbor and it truly shocked me at how easily it went through it. I bought it after attending a "Woodworking show" and they had it on display, turned on, sitting on the table and it just sat there, did not move.
The only downside, and that would not stop me from buying another, is the method of blade removal and or change. To me, it is a little cumbersome. Which, translates into four stars rather than five.
Other than that...this saw, to me, was well worth the investment.
