Umm, I have a few, and uploaded them onto Sendspace for you here (http://www.sendspace.com/file/mxow30). (I'm too lazy to upload them individually, so it's just one big zip file.) Hopefully that'll get you started.

Oh, and I seem to remember there being lots of PoT doujinshi at the Download Central part of the Aarinfantasy forum (http://aarinfantasy.com/forum/forum.php), but I think you have to be a forum member to access them. Still, it might be worth checking out?
