Madburg: I will tell you that pens are just as addictive and that after 50 or so, everyone you know will have a pen and then they start to collect in storage cases, etc. As Little Black Duck said in another post :Not a slimline. that's the other thing. I have never really liked the ubiquitous slim line pen and so shy away from them. But even then, you will amass a number of ball point, fountain, gel tips, etc. But, all I can really say is Enjoy what you are doing. It the act of creation that is the enjoyment; you'll figure out what to do about storage and display. Good luck to you!
