That was a problem when I first started a few years ago, so I used a very simple algorithm that didn't have non-alphanumeric letters. About 3 years ago I came up with a better algorithm, and now I use both. The simpler one on throwaway sites, which tend to be the same sites with insecure password requirements, and the more complex one for everything else. The only problem I still occasionally run in to is when a site requires a password change for whatever reason. I have a couple of minor permutations on the algorithm that I use in those cases, but sometimes that does trip me up.
