Mmmmmm..... coffee.
I own it and used it once to create a friend's site. Their latest version is MUCH better than earlier ones. You know how you can edit your site in the Design view with Dreamweaver? Well it used to be you couldn't do that with CoffeeCup. Now they've made it so you can edit in Design view so that's a huge improvement.
It also comes with a lot of fun javascript scripts you can use to enhance your site. I like it. If I hadn't fallen in love with Dreamweaver I'd probably be a CoffeeCup user. I always recommend it as an alternative to those who cannot fit DW into their budget.
