One thing you should watch out for is additional mouse\keyboard button support. I bought some cheap generic KVM, and it works, but the extra buttons on my mouse and keyboard don't work. The keyboard isn't a big issue, but I use the side buttons on my mouse all the time, making the KVM pretty much useless. If you don't use your extra\keyboard buttons then I guess it isn't an issue, but if you do, then thats just something you should look out for.
