First, are you looking to buy just a flat screen monitor or a whole new computer? If you just need to replace the monitor, you'll find lots of options in stores at Best Buy or Walmart. I suggest going and looking at a few side by side if picture quality is important to you. If you are comfortable with ordering online, try www.Amazon.com, www.walmart.com, and www.tigerdirect.com. If you really want a cheap monitor, check used ones at your local www.Craigslist.com
