I love to see new things. If you think Google is already very good you'll be surprised that even better things are coming up.
Quintura is new (a year or so) and you'll be impressed at least by their interface. If you are searching something difficult it surely will save you time navigating through pages of typical Google results. The good thing I like is that you could easily adjust keywords you entered, i.e. changing your mind along the way. If it is a difficult search you are unlikely to have guessed the right keywords. By adding or removing keywords you could very quickly shorten the result page.
If you prefer desktop client they have one here. If you have Google desktop installed Quintura can search through Google's index and give you instant results.
