Very cheap tactile switches

[Screaming_Rabbit]

I'd like to buy very cheap switches for my test setups only ...

1. Where to get the cheapest ones?

2. Can I run into problems with cheap switches (specially when multiplexing)?

Thanks and greetings

I bought a lot of tactile switch on ebay, always cheap... But they need caps (and this is a problem for me for about one year now!!!!).
