There's a free copy of NetObjects Fusion on the April 2005 cover disk of PCA.
I would not recommend shelling out on Dream Weaver if you're new to web design. It is a powerful program, but has a steep learning curve by all accounts.
No there are not any free programs that are just as good as Dream Weaver, but there are free options that are viable such as Open Office, and WYSIWYG programs like Serif Page Plus 9, that are cheap, and very easy to use.
NetObjects Fusion gets my vote, as it is free on the cover CD, WYSIWYG, and easy to use (if you have done DTP before). It won't limit you as you progress to more ambitious designs.
