tempted to sell my t3 and get this to save a few bucks. My boss is a huge Nikon lens collector, so I'd be buying this just to use some glass normally out of my price range. Not sure if the camera itself is better than the Canon.
Wow, lucky you! Do it man, always go for the lens availability. The lenses cost more, and they affect the photos more than the body.
Oh yea, and the D3100 is definitely better than the Canon T3 anyway. Partially IMO of course.
