---

### **Cons**

1. **High Initial Cost**

FANUC components, including CPU boards, are **premium-priced** compared to generic or third-party alternatives. The cost of a **new or refurbished A16B-2202-0853/01A** can range from **$1,500 to $3,000 **, depending on condition and supplier. This may be a significant investment for smaller shops or those on a tight budget.

2. **Limited Availability of Refurbished Units**

While FANUC parts are widely available, **authentic refurbished units may be scarce or expensive** due to high demand. Some sellers offer **gray-market or counterfeit parts**, which can pose **risk to system stability and warranty coverage**. Always verify the **source and authenticity** before purchasing.

3. **Dependence on FANUC s Ecosystem**

If your machine is **deeply integrated with FANUC s proprietary systems**, replacing a single board may require **additional software licenses, calibration, or recertification**. This can add **hidden costs** in terms of **programming, diagnostics, or reconfiguration**.
