Macromedia Dreamweaver
Dreamweaver is a proquality tool that has al the power and flexibility you could ask for. It is also voted Editor's Choice and one that I would recommend. For hand coding, Dreamweaver calls up an external source editor and allows for integration with the changes into WYSIWYG view automatically.
NetObjects Fusion
Fusion, much like Dreamweaver takes a different approach. It's considered a true WYSIWYG tool to a desktop publisher than an HTML editor. Its as simple as dragging images, text, and other objects anywhere on the page and simplyh drop them in. It also lets you insert untouchable code into pages, so you can tweak where you want and let Fusion handle the rest.
Adobe PageMill
This is an inexpensive tool for beginners and it works just as well as the others mentioned above. Adobe's popular PageMill editor has plenty to offer beginning Web developers with minimal HTML skills, but not very many web developers use it. It can perform basic tasks, but when compared to the other high-end tools, it cannot view both the WYSIWYG layout mode and the document source at the same time, as you can with Dreamweaver.
Microsoft FrontPage 98
If you already familiar with and use Microsoft Products, there isnt a more compatible tool than FrontPage. This is the most complete of all WYSIWYG tool on the market. It combines comprehensive site management with easy-to-use page creation tools, and includes for advanced authoring. I enjoy this tool and recommend this to beginners to intermediate users. Some advanced web developers can take advantage of the view modes and the ease of use is the most attractive.
