If you're looking for a ps3 stick, and dont already have an HRAP2, you should try to find a Sega Virtua Stick High Grade.
All sanwa parts: stick AND buttons (Hori only uses a sanwa stick with hori buttons).
best stick ive used, including some expensive custom stuff (though the custom sticks LOOK awesome).
Hori RAP with sanwa buttons swapped in is great, but i like the size/shape/weight of the sega stick a bit better.
