Look for 4 port KVM switch
 

With 2 PS2 and monitor options. Any recommendations?

I use one from belkin (www.belkin.com)


One similar to this one: http://catalog.belkin.com/IWCatProdu...duct_Id=260736


And I love it - pressing the scroll lock twice + a number 1-4 will take you to the computer :D

I use this one at work:

works great.
