I have one that is similar from H.F. I do not see it on their website anymore, but it was in the same price range. The one you liink to must have replaced the model that I have.
The one I have is J U N K Y, but works. My motor appears to be smaller than the one you linked to and the adjustable blade roller guide things look to be different, too. The motor on mine had a plastic fan that didn't circulate any air and looked to be made out of the same plastic that milk jugs are made from. After the saw ran for 20 minutes, I shut it off and the fan melted off the shaft... twice. The replacement saw did it too. So now I just run it with the fan missing. It gets very hot, but I haven't managed to kill it yet.
Also, the blade pops off often. I have tried many adjustments, by I ended up having to cut slow by increasing the tension on the counter weight spring. My advice to you is take the cheap product insurance on it, if at all possible. And take the saw back every time it croaks. Also, take the advice about the bi-metal blades. I couldn't find any at H.F. and am looking for a local source.
To summarize, that saw that you linked to looks to be an improvement over the model they sold earlier in the year in the same price range. However, get the insurance on it. It should work O.K. for home use, but not any kind of production stuff.
