I had rolled my own PDF generator with an entire layout engine before I found this. I was disappointed but immediately threw it all away in favor of that, because it’s so much easier. It’s just soooo damn much easier to use than keeping adding features to a custom engine. It handles CSS print stylesheets pretty well too, so you get to do all your page breaks and everything and the output is pretty clean and usable.
I think it does generate mildly heavier/complex PDFs but at least it looks great.
