Brand new in box. It's an unwanted gift and I could do with the cash moreso than the camera at the moment. It's listed in a number of places so be quick!
see amazon for details (and price ;)
As a quick run down of important factors, consider the LiveView which is executed better by Sony than competitors IMO, 14.2MP sensor (ok not the end-all-and-be-all but not insignificant either), and importantly in-body image stabilisation (which removes an unnecessary premium on future lenses and allows you to use comparably lower ISO settings).
A trade with a canon 450d lens kit would be very tempting also!
