I own a DeWalt and have tried a Excalibur. I love the tilt feature of the Excalibur. It has the same blade clamps as the Dewalt, and seems to be built to last for many years.
I am a top feeder and love that the upper arm of my Dewalt Lowers the blade into the hole by gravity.
On the Excalibur, the upper arm stays up when you lift it. You have to pull it down to feed the blade. Bottom feeders will like this feature, But I Don't.
On the Dewalt the tension is adjusted with a lever on the front of the upper arm. On the Excalibur, there is a lever on the upper arm to tension the blade, but to adjust the tension, you have to reach to the back of the upper arm and turn a knob. I like the DeWalt system much better.
Money was not an issue when I was looking for a new saw. I gave the Excalibur a good workout, But chose to stay with Dewalt.
