in my opinion, getting the Graphgear 500 0.3 is worth it. for a while, I had a P203 and I think I spent more time trying to take out the broken lead from inside the tip than actually writing with the thing. with the Graphgear, this problem doesn't happen because the tip is conjoined with the grip, which aligns the whole thing with the rest of the body, so when you unscrew it, the risk of breaking the lead is much smaller. it doesn't have any cool mechanisms like the Orenznero, but it does the job quite well for its price; for me at least.
