In complete agreement, here. BBEdit is the way to go. I use the full version in combination with Dreamweaver -- they talk to each other like a dream, and BBEdit has a grep function that makes it indispensable for me.

Haven't used BBEdit Lite in years so I don't remember what the feature set is on it, but full-blown BBEdit even has ftp support built into it, and a bunch of other nifty things.

*And* it won't put anything into your file that you don't want to be there, *and* it's just a gorgeous, elegant editor for plain text files of any kind. Yay, BBEdit!
