What semitsu sticks/buttons can I just drop into madcatz se stick?

I want some slick ones but all I could find was the screw ins. I need snap in buttons. Which ones can I get and what of the stick?

30mm snap ins.

Check out Lizard Lick and Akihabarashop.jp.

Normally Lizard Lick is faster because they are in the states, but at the moment they are getting slammed with orders.

So I would go with Akihabarashop.jp right now even though they gotta ship from Japan.

All the really cool ones seem to be screw in though.
