usb switch for keyboard & mouse (like kvm)

[shadowlord]

hello all!

i'm searching for a kvm switch without the v for usb keyboard and mouse.
controling 2 computers with one keyboard and mouse.

i found a lot like this one intended to switch peripherals like printer or scanner but nothing like k/m

i think basically it would work but is it lag free enough for my gaming pc?
has anyone experience with this?

or is there a wireless solution with 2 reciever?

only thing is i'm used to trackballs (especialy the one i'm using) which narrows down my options.

any help would be appreciated.

I'm looking for the KVM Setup with USB instead of PS2 - I'm unlucky thus far. I'll probably just buy four usb extensions (~$5) and do the swapping manually.
