Dreamweaver MX is the way to go.
I've been a designer with intel for years and we used to swear by Homesite...but then Macromedia incorporated the best of Homesite with the best of Dreamweaver in making MX. You can design using the Homesite interface, the Dreamweaver interface, or the new MX interface.
I can't even begin to describe all of it's features, but it supports everything from HTML to XML...and the code is clean and that's what counts.
Forget GoLive...don't event think about FrontPage.
