Cost of product is a big item to consider if you are on a tight budget. While the big names are nice to have, they tend to be expensive.
Clean HTML code is another item. The cleaner you can make it compared to the official HTML specs, the more compatible it will be. You may not have as may bells and whistles but you also have fewer hassles.
You may also want to look for a 'Publish to CD' feature. If you stray too far outside the standard CD-ROM format with your folder/file naming conventions, you can have major problems writing to a CD.
Note that a lot of word processors and such have options where you can output to HTML format. If you don't mind the garbage these output behind the scenes, they could function as HTML 'editors'.
For that matter, you could always publish to Abobe's PDF format and output that onto CD, with a bare bones web page for access to the files.
