The slim model was announced about two months ago. They dropped the price of the old model to get people to buy it and clear room for the new model, which is still $199. And you bought one, so I fail to see how it's bad business.
You might do well to try your local used video game store, or Funcoland (if that's still the name of it) chain. If buying a used one isn't an issue. I suppose that the battery would be slightly more worn down, but that won't likely be an issue.
