Looking for a good Website software package

Hi,



I am looking for a good website creation software package. I know iWeb can do it...but it look very basic.



I know iWeb is made to really do 1 site unless you get a 3rd party add-on called multi sites.



I know my way around creating sites. I used to use Frontpage.



Now I am on a Mac and would like to use a current Mac program.



Any help/suggestions would be great.



I would like to stay away from the heavy coding packages and get something that is wysiwyg.



Thanks in advance.
