Hi Steve--
Yes, we are still using/selling/promoting our PDFX product. It has turned out to be quite reliable and durable, we're pretty happy with it, and we can recommend it without reservation.
The big question, however, is: do your needs and PDFX's capabilities line up well? If your objective is to create PDF docs from A-Shell, then PDFX is likely your best bet. If you're producing or want to produce PDFs from reports that originate in A-Shell, then great; PDFX will do the trick. But if your original materials are coming from a scanner or a PC or some non-A-Shell source, then PDFX is probably *not* the best possible tool.
I hope that helps, let us know if not.
