I bought the Bosch 3915 from Amazon for $350 in 2004 after it had been
discontinued. Sonoma was correct about the detents getting sloppy
after a while. (The detents on the mechanism that slides the blade
guard out of the way.)

If I had paid full price, I'd probably be unhappy but the problem is
not critical. Just some resistance at the top of the pull. I used
masking tape for a while, now I just live with it. It still cuts nice
and square. I have to use force to start the pull but not enough to be
dangerous. When it's hooked up to the shop vac the dust isn't too bad
but there is some. I've got it on a homemade rolling stand with hinged
wings.

I'm not completely happy with it because of the detents but it's the
most-used tool in my shop. I can say that while the detents got kind
of sloppy pretty quick, they never got worse and it doesn't make the
saw unusable or less safe.

I had heard that the later models dealt with that detent issue. Can't
say. Over the last five years this one has gotten a lot of workouts in
many major projects and a lot of "We'll just knock a half inch off
this and she'll fit just fine" uses. Pretty dependable. It's the one
tool that always gets used in any project. Sliders have stayed
adjusted. No slop anywhere except for that detent.

I consider it worth the money but if I'd spent 500 and change on it, I
would probably not be so happy. :-)
