You can check RS Components to see if they have what you are looking for, however they are more of a general electrical component store than an arcade one, but they have an SA branch and do courier delivery.
Although based in Cape Town, Netram do deliver nationally, are reasonably priced and stock classic arcade buttons/joysticks (I believe Arcade Finger Twister was made using Netram buttons): http://netram.co.za/
I'm quite partial to the more industrial style switches of Mantech though: http://www.mantech.co.za/
Unfortunately neither of them stock IPACs afaik. I will definitely be looking into getting some IPACs in the near future, probably by ordering overseas, we can look into doing a group order (though this would be post-broforce).

Here are the links for buttons and joystick switches, not sure what iPacs are.
