I use a 8 1/2" Hitachi on a track system. It works well and it's been reliable. My prior say was Porter Cable, another good saw. But I think all the major players make good saws. I don't think you would go wrong with any saw from DeWalt, Bosch, PC, Hitachi, or Milwaukee. And many others I am sure, but I havene't been impressed by products from Skil, B&D, and a lot of the Sears saws. The BEST is probably Festool. Absolutely NOT what you want, but you can learn something by operating one and use that knowledge in evaluating other saws.
- How easy is it to set the depth of cut? It's dramatically safer and more practical to only cut slightly deeper than the board you are cutting. ("Practical" because you end up ruining less sawhorses, bench tops, etc. At least that's MY experience.)
- Does it have a blade brake? They aren't instant, but the blade spins for a MUCH shorter period.
- How smoothly does the blade guard push out of the way when you saw into a piece of wood?
- How easy is it to pull the blade guard up when need be?
- Is the base robust?
- There are other things, but they are not that important, IMO. How easy is adjusting the angle/ (Almost everything I cut is at 90 degrees.) How easy to change the blade? Is there any provisions to help dust collection? Is the cord molded so it somewhat stays out of the way? Does it come with discount coupons for Victoria's Secret?
And, a good blade makes a difference. I suspect all the good saws come with a pretty good blade, but it will cease being a good blade after you've made quick work of a few dozen pallets and other junk work. Keep a **** blade for the junk work.
