Answer:
Getting an LCD at that price that's good for gaming is tough. On an LCD, you really want a 120 Hz refresh rate for gaming, but you'll be challenged to find one that's anywhere near your budget.
Instead, consider a plasma set. Great for gaming, and close to your price range. See the reference for a possible choice from Walmart.
