If you like the WYSIWYG (What You See Is What You Get) features of Microsoft Frontpage but don't like paying the $160+ dollars for the software, then try:

AOLPress

It's a old HTML editor that has turned into abandonware. Despite it's age it still has all the features you really need. You can edit HTML in both WYSIWYG and raw format. It's a very small download, so it won't hurt to give it a try.
