I would say use SHA1_Pass and never store, synchronize or forget a password again. I'm biased though, I wrote it and use it daily. It's entirely free, cross-platform (GPL licensed) and you can get the source code from github.

Edit: Also, SHA1_Pass does not rely on websites or anything remote from your device to operate. It just requires you (the user) and your brain ;) That's the biggest reason I wrote it.

I use Passpack. Uses a password and a packing key -you have the option to use a yubikey as well.
