Looking for a KVM suggestion

[Kinex]

I've been playing 5 shaman on 3 pcs via keyclone, got them at 39 now, and decided i'd rather have a 5 pc wireless keyboard + KVM (for video/mouse) setup.
so after reading a few kvm reviews, i'm looking for suggestions, i want a push button switch (or programmable) that transfers the video relatively fast
i'm not sure what to expect as i've only used 2 port KVM switches, which were extremely sluggish on the switch, and i stopped using them altogether.
how many seconds roughly would i expect to wait on a higher end kvm switch for the swap to occur?

The ones with the most speed seem to be from Vetra.

If I may offer advice.....don't go the wireless route. it's not as reliable as you'd think. I tried it as well, but ended up going the hardware route with a keyboard multicaster from Vetra. It's sort of spendy, but easy and certainly reliable (the PS2 version at least)
