Several machines will cut Spellbinders dies - I've linked some of them below.
First off, the Spellbinders dies are different in that they will emboss as well as cut. With a Cricut, you only get the die cut, but with a Spellbinders die, you can also emboss it. If you click on the products, you can also find videos, etc that explain them. The Spellbinders website is also very helpful.
If you look at the picture below, you can see how I embossed the die cuts (crown, decorative circle and die cut behind it).

You can also use the die itself as a mask and ink/chalk/spray over it to create a die cut like the pink/white one on this card below - the same technique was used on the card above (yellow portion)
