As said - I don't use noise reduction software so I am not in the market to buy this. (and I have Nik and PS anyway)
However - I like to know what is "out there" and perhaps we all learn something new by checking what is available.
It seems to have been around for a good couple of years and has had good reviews on
Luminous Landscapes (and other sites) and I quote:

Neatimageis in my experience the most effective and comprehensive program available for reducing and even eliminating noise in either scanned or digital original images

It all starts with profiling the image, either by loading a camera profile or sampling the image and performing an auto-match. Neat Image also reads the EXIF data to get the model. Setting the sampling patch can be fiddly but once done you can move on to the noise filter settings. There’s also the option to sharpen the image. The results are often nothing short of amazing.
