NVU has a dismal future. It hasn't been touched since about mid 2005. It kind of got grabbed up and it looks like there was a spilt in the developers. It appears that there is a fork of the product that isn't getting very far. Google it and see.
As I have been looking at packages, mid-range to high-end, and comparing that against putting together individual editors, css managers, etc, it really looks like I will end up with DW CS3. It turns out to be cost effective.
I wish I could spring for a CS3 package, but in looking at what is packaged, and the costs, I will just settle for the DW portion. At least it supports CSS and AJAX/Spry. And tables - ugh!
