You'll get over that little hurdle once you realize that you can dump the anxiety of remembering a hundred password variants for different sites. And realistically speaking, you're probably not even using a hundred variants...or possibly even 10. If you're memorizing passwords, chances are your re-use frequency is nonzero.
What's important is to keep a backup of your password database in a few places. I use KeePass because I have no desire to keep passwords, encrypted or not, in a cloud service. I also don't find value in browser integration (possible attack vector?). I'm generally very DIY-inclined anyway. Your preferences may vary.
