Is there any affordable web design software for Mac OSX?

I can’t believe there is nothing readily available out there. Specifically, the things that come with a Mac are designed for personal use like blogging and podcasting and photo sharing, or newsletters and publishing. Nothing really business related.

I was looking for MS FrontPage for Mac but they don’t make it anymore. And they don’t have anything comparable that comes with the MS Office suite for Mac. Anything out there compare to FrontPage that doesn’t sink the budget? I need to do a business related web page, and everything I have tried doesn’t work. Does MS Word do a good job if converted to HTML?
