Somehow this site made it's way to my email in box, and it may be worth a look:
It's rollyo.com. According to the site:
"Your searchroll is a collection of the sites you trust and find useful. It's a personal search engine you create to provide relevant results from a hand selected list of reliable sites. You can make as many searchrolls as you want. Just enter the sites you want to search and you'll be off and rolling ."
It may be a time waster, or it may be a useful tool. You decide.
