We started out with Dreamweaver way back in the day. Back then it was iffy because some bugs needed to be worked out. Later when they released CS2 most of the bugs have been fixed. It no longer created any invalid code.

While we create websites using mostly the code view option, we occasionally use the design view to speed up certain aspects of the work. We are able to produce valid xhtml every single time.

CS3 has made the design process much easier. It is worth spending the money and avoiding crap software like Frontpage.
