If you follow Joy @ http://www.obsessedwithscrapbooking.com/ you have already read about this web site.
I find this the most user-friendly search and more thorough than Cricut's own searches on Design Studio and Gypsy. I have used it several times since Joy introduced it and think it is a great asset for Cricuteers.

Thanks for stopping by,
