I recently setup my own google powered search engine using google's fairly new custom search engine (CSE) service, free as always. Setup was a breeze, and allows for fairly good customization. You can also link it up to your Adsense account and generate revenue from your traffic, which is good for me and helpful to you! It also allows you to integrate with the Firefox searchbox...
by linking an xml file in the head following the opensearch format, supported by most modern browsers. Take a look at my xml file to see how easy it really is.
Support me by setting my engine as your homepage, or integrating into your Firefox/IE7 search bar! Suggestions welcome for enhancements :]
