LCD Monitors with Dead Pixels/Columns for Sale?

The Other White Meat asks: "I want to put a computer in my kitchen. For space reasons, I want to make it an LCD; a 15" screen would be perfect. This monitor is going to be exposed to harsh conditions (flying food, jumping cats, general mishandling). I don't want to spend so much money on it that if I came home and found it broken that I would be upset by it. I figured there must be plenty of places that will sell LCDs with dead pixels or columns, where I might be able to pick one up in the $50-100 range, but so far I have found nothing. Surely there must be a market for 'Grade B' LCD monitors, for precisely this sort of low life expectancy sort of usage? So fellow readers, can you succeed where Google® has failed, and lead me to the cheapo LCDs?"
