BestBuy is offering a really good deal on the Nikon D5100. Just $489.99, that's about $210 off. I have seen this camera occasionally go for $600, but never sub $500. I talked my brother, Linkara into picking one up as an HD Camcorder. Why? Well I first got turned on to this camera when Nash bought one and posted this video.
I bought one for my employer at the time and did the mentioned firmware hack to remove the video capture limitation.
And wow. It's a pretty cool camera. I really like that it has a Microphone in. And the included lense isn't that bad either. Linkara will be pairing the camera with the RODE VideoMic shotgun Microphone I recommened to him after reading/watching this review at PCper.com
