Dual monitor KVM experience?

[Velonautic]

I just upgraded to a new machine and would like to keep my old machine for internet use. I have been using dual monitors for some time and would like to install a kvm that supports dual monitors. Can anyone recommend one that they like. They seem pricey and I would hate to get something that does not work.

do you also need to use your mouse and keyboard on the same machine? i use this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817399032
and it serves my purposes well for switching between my nettop and desktop.

specifically I need dual DVI viewing capability

What I am looking for is a switch that supports dual monitors for two PC's
