Anyway, I settled for VeryPDF. $10 cheaper, fully featured, simple clean interface. During the 2 day trial I didn't have to squint at my screen, browse through to find how to do something or fight against the interface in any other way. It was much nicer on my meager hardware resources too.
As for the other two I decided to pass on my web host offer. I'm not on the PageRank freak market, I understand how to develop search bot friendly websites, and I can register the website manually on the several directories and search engines.
But I had to confess here my annoyance at these interfaces following Vista interface guidelines, which aren't even toggable, and that seem to be populating the market, forcing XP users to accept them or find something elsewhere.
EDIT: PS. I have nothing else to add to this thread.
