#### **Cons**

1. **Cost**

The Proto 2000 GP30 (#87) is not an inexpensive model. Depending on the specific version (e.g., with sound, DCC compatibility, or additional features), the price can range from several hundred to over a thousand dollars. This makes it a significant investment, especially for hobbyists on a budget or those just starting out.

2. **Maintenance and Durability Concerns**

While Proto 2000 locomotives are generally durable, they can be prone to wear and tear over time, particularly with heavy use. Components like the motor, sound system, or couplers may require occasional maintenance or replacement. Some buyers report issues with the motor overheating or the sound system failing, which can be costly to repair.
