Hey I found these: http://www.lik-sang.com/info.php?cat...ducts_id=7263&
They're pretty cheap and make using the analog stick on the PSP less arkward. They are raised higher than the regular one which is a blessing in itself but also have a larger surface area, and have a slight rubber grip. Also you get 5 different types so you can change around depending on your personal prefernece. I'm surprised not amny people have picked them up yet, I certainly find use of my PSP much easier now.
Anyway now I can COMFORTABLY play Wipeout Pure with the analog stick. The only downsde is it makes it *slightly* harder to get to the d-pad
