2. **Electric Die Cutting Machines**:

   - **Sizzix Big Shot** is a well-known electric model that can handle various materials including paper, and it's easy to use without needing an external power source once it's manually started.

3. **Computerized Die Cutting Machines**:

   - **Cricut Maker** is an advanced cutting machine that can handle intricate cuts and a wide range of materials beyond just paper.

   - **Silhouette Curio** is a desktop cutting machine designed for precision cutting of materials like paper and can also accommodate pens for drawing.
