MS FrontPage is a poor app. MS is inept when it comes to building well coded sites and FP just reflects that inability. It spits out the most jumbled code I've ever seen. It's remarkable the web-pages made with it ever work. Very basic layouts (such as the LL) may be fine, but as soon as the site becomes more complicated with design...
For less money, you can get far better web design tools such as
Dreamweaver. It's one of the better WYSIWYG (What You See Is What You Get, pronounced "Wizzy-Wigg") editors out there.
For my editing on the PC, I used
TopStyle. I can't recommend it enough. It is not a WYSIWYG editor, but it has lots of tools to help you code a clean, well functioning site using XHTML and CSS. On the Mac, there is no HTML editor as good as TopStyle but there are good text editors such as
BBEdit or what I use,
TextMate. These aren't for the uninitiated but I thought I'd mention them for anyone else out there.
If you are on the Mac, you might want to check out
Sandbox. It is a WYSIWYG that is simpler than the likes of Dreamweaver but may not be as functional. It's has gotten allot of positive press however as being like Apples iWeb but more flexible.
