Now that's surprising. D5100 was selling around 700 bucks few months ago and T3i was slightly cheaper than that. D7000 selling for less than 1k is another new thing I'm seeing. It used to be about 100 bucks cheaper than 7D 3-4 months ago, now the price difference is quite large. Looks like Nikon is having hard time competing with Canon and lowered the price  or maybe they're launching new models and wanted to clear the stock. If anyone loves Nikon, this might be the time to grab them.
