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!
