My brother has a problem. He goes through keyboards like crazy. He used to smoke near them, but gave that up. Now he just eats and drinks near them, but spills stuff into the keyboard and the keys stick. I gave him a Dell used keyboard (worth about $4 or $6 used), and keyboards can be bought for cheap these days, but still wear out fast.

He bought keyboard covers, but there are always an odd key or two that don't fit. Are there special keyboard covers (membrane that fits over the keys, not those hard plastic covers, but the rubber ones) that match a certain keyboard? He wants, of course, the kind of keyboard that they don't make anymore. The one that feels good to type on, if possible.
