really depends on what joysticks where used in your local arcade... This will give YOU the best authentic feel.
I personally LOVE happs supers, and the pacman anniversary 4ways (ones with microswitches). The supers are a great all around joystick (round so works great with gyrus and such, but still playable with fighting games)... and the pacman joystick feels like the originals (pretty close anyway, might not want to do a side by side comparison... without it, it feels original).... Both are cheap.
As for one that can move back and forth... not sure.
