It's my first time to own a miter saw, and I bought this DeWalt to replace a Ryobi that I had gotten a couple of weeks prior.
I wanted an entry-level saw, and was shopping primarily by price. After trying out the Ryobi, I realized I needed a better machine, so I returned it and got this DeWalt. My primary reason was the accuracy and stability of the angle selection. This DeWalt clicks over to 45 or wherever, and stays there. Not 44, not 46, but 45. I felt like the Ryobi I had first purchased was hit-or-miss when selecting an angle. There was too much wiggle, and I didn't think the cuts would be repeatable with enough accuracy. This alone was worth the extra money that I paid for the DeWalt. It's well-built, and feels like a more professional machine. My first project was a leather stitching pony, and I'm happy with the results. I think the DeWalt will be a long-lasting addition to my hobby shop, and will work well for the projects I have in mind.
Having said that, there are two things that disappointed me: 1) the bevel locking knob on the back of the machine is plastic, whereas the floor model I saw had a nice anodized aluminum knob, and 2) there's no work clamp included with the saw. DeWalt has one available, but it's overpriced, in my opinion.
Those two exceptions were disappointing, but the quality of the machine and it's operation keeps me happy with my decision, and I can recommend this DeWalt DW713 for hobbyists and professionals.
