I posted some months ago on the same topic and was advised to try HTML KIT as an alternative to Homesite. I tried html kit and did not like it enough to make the change. I like a text editor that helps me out a bit without writing the code for me and didn't want to use Dreamyweaver or other wysiwyg builders.
Maybe I am the only one who didn't know but I just found this editor which is good enough to pry me away from Homesite - webuilder 2005. Anyone else tried it?
