I realize it's not on the same level as a lot of the pens that are discussed in this forum, but has anyone tried the Grifiti TagTool fountain pen? I recently bought one as my first non-disposable fountain pen. I enjoy it, but I also have nothing to compare it to besides a disposable Pilot Varsity. What are your thoughts on the TagTool? How does it compare to something like a Pelikan M200?
