PHP and PDFs

Wasn't all that long ago that using PHP to generate and manipulate PDFs was a painful, gruesome process. Installing either of the 2 PDF extensions into PHP was a complete nightmare.
A couple of years ago I discovered FPDF.
I'm using it for automated invoice generation for the small amount of freelance stuff I do. It took a little work to get the blank invoice tweaked just right, but I've printed off the PDF generated by this tool and a real invoice I create in Quickbooks, and there is no way to tell the difference, they are identical in every way.
Has anyone else tried this tool?
