Sony Nex 5r or something similar?

Hey everybody, looking to get my girlfriend a decent, first time camera for christmas this year. I'm looking for something under like $600 -700 but with decent low light features and the capability to use interchangeable lenses. I've read the review for the Sony NEX 5r and am pretty sold on that compared to what else is on the market. Just wondering if any of ya'll have experience with the 5r or have any other suggestions. Thanks in advance!
