Well, that's your job. Try out a few and see how it goes for you. The one that allows you to export a static site most reliably is the one to use. Wget shouldn't give you any trouble with CSS - it reads it to hunt for background images etc. Javascript is only really a problem if it is generating URLs for server side scripts. If it's generating URLs for content that already exists on the server then wkkay's tip to copy the static content separately from the wget will handle that.

Javascript-only solution might not work well across all browsers and search engines.

IMHO find-and-replace is the easiest solution for static contents. Much easier if your editor can do regular expression
