do not buy to shmup's these joysticks, they are not suitable to these games.
Use electronic joystick optical (P360), Inductive (Suzo), Ultimarc Ultrastick360 (you have to buy restrictors).
if you want mechanical sticks use Mag-stick, simitsu LS-40 or Sanwa JLW (but only Japanese versions)
according to me suzo inductive is the best.
