I hate to disagree with just about everyone out there but I've had a Belkin OmniCube 4-port model. Yes you do have to have it switched to the correct computer when powering one up or it doesn't recognize my mouse (Logitec Track ball, old school 3 button style, wheel mice are for pussies) and that is a minor problem. I do use the Belkin cables. I suggest getting the 3 cables molded together, I have zip ties holding them in sets. Don't forget to color code them. I can't tell you how many times I unplugged/plugged the wrong cable before I did that. Yes they are PS2 only but you can use USB/PS2 convertors to fix that as long as you don't plug more devices into your keyboard. The hot key combos are great for the keyboard, well to switch between computers (linux/win98) that is. The cost wasn't too bad. Cube and 3 sets cost about $250. Well below your cost.
