I design websites as well. I actually use Microsoft Web Expressions and Kompozer. Web Expressions is just like DreamWeaver, I use it while I am working on Windows computers and making larger changes. Kompozer, I use when I am on my Linux laptop, and when making smaller changes that do not require changing the master template, or anything of that nature.
The main reason I use Web Expressions is because I got it free through the college MSDN.
