Those reverse indiglo gauges from procarparts.com on ebay work very well. I bought a set from him, and they look even better on the car than they do on the auction. I am very happy with the appearacne, and the installation was a breaze.
I have both installed, it is a different type of glow (very similar in shade though). The gauges are a little more sharp than the HVAC indiglo overlay. It does look good w/ both installed (IMO anyway).
