Do You Use a Password Manager?S

We could all use a good self-audit on our passwords—bank accounts, credit cards, e-mails, social networks—but is it better to just let a password manager handle all of our passwords instead? Or should we still cook up a different password for each account on our own? What do you guys do?

People swear by password manager services like 1password or Lastpass but I'm not yet convinced I want to go through all the work of figuring it out. I'm hoping there might be a better solution, at least one that strikes a nice balance between ease of use and security. I don't know. Do you guys have any suggestions? And if you do use password managers, which password manager do you prefer?
