I got me a belkin omniveiw four port also. I like the belkins (Hawking Tecnologies has a similar version I hear works great and is quite durable) because it has port simulation. The others, (generally ones you don't need to plug in to the AC outlets, just a manual switch) are pretty much tantamount to just yanking out the cord and pluggin it back in to the other pc. Most mother boards are cool with the keyboard, but many are not with the mouse. Though more and more motherboards are allowing "hot-swappable" PS/2 ports, there are still many that can't do this. The best way to find out if you board will allow it is to unplug the keyboard and mouse, wait a couple of seconds and then plug them back in. If all is well, then you can use whatever you want. if not, then you might need two mice anyways and just share the keyboard and monitor. Also, most electronic KVM's will have a male-female cable for the video, not like the manual ones that are male-male. So if you do buy, be sure you get the right video cables. And if you run a high resolution on your monitor, you want to make sure your KVM switch can hadle it, other wise, you will get ghosting effects and fuzzy lines. (you can also get this with poor cables or ones that are too long/extended too far, good quality ones should be between 10-25 bucks) All in all, belkin was cool, since it has a metal case, had port simulation, is small, and is black (very stylish if you care about that). The other features did not factor into my descision. I also have had plenty of belkin equipment in the past and all of it is still working. I paid $112 for just the box, and cables off of e-*ay for $5 a set (found them online for $9). Good luck!
