Looking for a Cap repeater (ICO)

[Rolling Stone]

Hi
I am looking for a cap repeater, think it is generally referred to as an. ICO
Also want to know what are the best quality switches that I can use on my tower and where do I get them, preferably somewhere in the west rand
Was thinking of using toggle switches, but someone warned that. They could. Give problems
