I don't know what kind of pens you buy. Magazines are no help. The magazines will list ten things that are great, but I am looking for that 1 that is the best, up to 100 dollars. That why I post here because Magazines are no HELP. I got tired looking at magazines so I want people reviews. So if you don't know then don't tell stupid things like you can buy pens and look at magazines. That's why I post. I am not interested in CAD I posted that I don't what that. It way out of my league.
