Google Search - REFERENCE Sites Only.

Hi.
I have created a Custom Google Search with REFERENCE Sites Only.
It's very easy to use, just like the regular Google Web Search but, it will look only on the indexed sites.
I have added so far: Hyperscale, Missing Lynx, Aircraft Resource Center, Large Scale Planes, Modeling Madness, Armorama, Mig Gimenez Blog, Perth Military Modelling, Track Link Modeler Site, Cybermodeler

Take a look here:
