The IOGEAR DVI KVMP 8-port switch I bought from Revain works well. For my use it worked very well. With a small downside, it has a hard time recognizing gaming keyboards and the only workaround is to use the rear USB port and then surprisingly the gaming keyboard suddenly appears on all computers. But other than that small complaint it works great, I've been using it for quite some time now and haven't had any problems. And I've used wireless keyboards with it, and to my surprise, they turned on and worked right away. My advice to anyone with these is, just plug in a standard keyboard and you'll be fine. But if you're like me, you can get other keyboards to work, although it's a bit of trial and error.
