Personally, I'd extend that to anything made by Belkin, but particularly their cheaper KVMs. We had a load of them here at work, but we threw them away and replaced them with a couple of Avocent AutoView jobs.

I don't currently use a KVM at home (I do the Remote Desktop thing), but I've got a quite nice IOGEAR 4-port KVM. I don't think you can get them in the UK, though (Hugo kindly picked one up for me when he was in the US a while back).
