I've been using 1Password for about six months now, and loving it. It can auto-generate passwords for you, so for most of my main sites now I actually don't know the password anymore.

The advantage of 1Password is that it runs on Mac/Windows/iPhone/iPad which are all the main platforms I use regularly, though this setup cost a little more than buying it just in one place.

A feature I quite like, and that made me feel somewhat more confident in trusting ALL my passwords to it - is that not only does it sync to dropbox, but you can visit the dropbox website and view a .html file to get web-based access to your passwords though a now-familiar UI.

(I'm just a happy customer, I don't work for them - and I've never tried a competitors products so this isn't a comparison)
