What web development software should I buy?

I am a very basic web designer...very new, but can tend to find myself around user friendly software. I am currently using FrontPage 98 and would love to upgrade. I see I can upgrade my FrontPage with Microsoft Expression Web, is this any good? I also hear a lot about DreamWeaver.

Here is the kind of site I have been making with FP98 :

www.kimbirdart.com

(Very basic, but it serves the artists needs)

Suggestions?

After being so disappointed with what FrontPage served up over the years (stuck with it) Adobe Dreamweaver (CS3) is worth the effort to learn as an ongoing experience (tons & tons or stuff). After a while you you get your own style and do not have to always being looking over your shoulder to see what Expression is messing up now. FrontPage = chipmonk that bytes- Dreamweaver= kind 1000 lb gorilla

Try Nvu - http://nvudev.com/download.php

It is good and open source (which means free)

or you could try Evrsoft First Page 2006 http://www.evrsoft.com/1stpage3.shtml which is freeware (free also)

The website is looking good but as a product that you sell the site is not so impressive .you can use dream weaver version 8
Even I had seen there is very less traffic on the website .I suggest you to get your site search engine optimized and reworked by good designer and optimized it by some SEO expert to get relevant traffic.

www.kimbirdart.com <=Impressive !
I would also recommend the Adobe pack. Try to get Adobe dreamweaver and Illustrator if possible or the whole pack Adobe CS3.
I'm a newbie myself and this is what I did with dreamweaver http://www.translationcentraljp.com

For web design applications, I'd recommend Dreamweaver. Though writing your own code may serve you better. It's free, you can do it in any text editor, you won't suffer from the "code bloat" brought on by design apps, and you'll have a better understanding of how the site works.
