"expensive shallow DoF" or software?

Once you know what you're talking about, discussion becomes easier.

Real (optical) shallow DoF can be had in 2 ways: through a lens with very large maximum aperture on a camera with an, at least FF, large sensor (expensive), tilt/shift lens (still somewhat expensive) or tilt adapter with medium-format lens (dirt-cheap). Examples on my Flickr stream with f.i. a Carl Zeiss medium format lens http://www.flickriver.com/photos/newmikey/

Software that does DoF manipulation? Never seen or heard of it actually - it does not exist. You can use Photoshop or GIMP to create the illusion of shallow DoF but doing that properly is quite complicated and takes a lot of patience and time. Examples on my blog about depthmaps here http://bing-photography.com/

Not every scene lends itself to either real or fake shallow DoF either.
