Of the 4 way sticks you can buy new I like the Ms. Pac Reunion stick and the Happ Universal.
I've had quite a number of folks tell me that the Leaf-Pro 4-way is the best experience they have had with "Pac" games since using the original, and that is
after trying the other options out there.

You really should try one, if the gameplay of the original stick is something you are after.
It does have a different base, so slapping it into an existing machine, made for the sticks you mentioned, isn't an option. But that's not too hard to get past.
