PasswordMaker allows you to tune the length and character set. You have to remember your site's password requirements, which is not so easy to do (usually they are only made available when you try, and fail, to change your password; in particular, only when you are logged in); but, in practice, I've found that using the default settings, and then using restricted settings (shorter length and A-Za-z0-9 character set) if that fails, works on every site I've ever used. This means that, if you are willing to endure the occasional inconvenience of having to re-enter a password, you don't have to remember anything per-site.
