I am looking to try a new style pen. I have been turning slim lines and wall streets looking for a postable cap pen. I am looking for a kit in the 15 dollar range and under. Nothing high end. I am looking for a kit the has good quality. It does not have to have a screw type post, it could be magnetic or anything but it has to post while using. Something like a navigator, vertex,etc. What is your favorite kit like this? And where do you get them?
