Looks awful and doesn't offer any great features. If you're on a tight budget then get Coda from Panic. It's a million times better than anything on the market, it kicks Dreamweaver's backside to next Tuesday. It's only around £40 to buy and it offers everything. FTP, Editor, Advanced Preview, CSS, Terminal and Reference Books all in the one window.
Panic Coda
One thing is, to get such as a great piece of software you have to use Mac OS. Sorry Windows users.
