Thanks for the tip. I slipped in under the deadline by just a few minutes (22 minutes) before the deal ended. I don't know yet if it gets rid of headers etc. but one thing it does do apparently is allow you to convert multiple files at once rather than having to do each one as an individual conversion. That alone makes it useful to a degree. Of course it doesn't have a Kindle conversion on the output but that's what Calibre is for.
