I agree wholeheartedly with the comments on Dreamweaver's templates! I used Frontpage for several years and used frames (YUCK!) to get the same design on every page. Now I use templates and love them.
The Dreamweaver Studio 8 is a great suite, I agree with that, too. It works really nicely with the graphics package (fireworks) and with flash. I'm doing more sites in less time that look better.
If you've been using Frontpage for a while, you'll probably be able to pick up Dreamweaver pretty easily. If you've never done Flash, I recommend a class because it's not as easy to teach yourself.
Since I've learned on this Forum that TABLES ARE EVIL I'm slowly getting away from using them. Dreamweaver has a nice interface for CSS, so that is helping a lot with my transition.
Definitely invest in Dreamweaver, get the Studio if you can afford it! Good luck!
