I was considering picking up a little giant ladder after seeing the impressive number of uses in the infomercial. A big ladder is fine for outdoor use, but I always hit the walls with my ladder when moving it around the house. I found this little giant review which is a video and tests the claims of the infomercial. It turns out that the little giant pretty much lives up to its claims.
They mention an alternative, which is cheaper. The gorilla ladder. Other than the fact that the Gorilla is not made in the US, it seems to be just as good and it is far cheaper.
Just be careful of the longer models, according to the Consumer Reports safety alert which claims they pose a hand and fingers crushing risk.
