anyone using KVM (Keyboard Video Mouse) ?

i have a windows xp sp 2 P4 3.0 1gig ram
i also have my Dell / Hackintosh P4 3.6 1.5gigs rams
i want a KVM that will work smooth with my Logitech Wireless Keyboard and Mouse while i play games
There are some that will give you a delay with your mouse playing games
Any help will be appreciated

Thanks Mac the World

I am using an IOGEAR KVM right now and it works great. I have noticed no lag while gaming, though I do have a small power problem (keyboard craps out if I turn on my fan, but that is fixed be unplugging the USB cable going into the computer.) I would highly invest in one.
