Those looking for Lightroom and/or Aperture alternatives should be aware you can get Corel's Aftershot Pro 2 for Mac as part of the MacBundles/Stack Social bundle with 7 or 8 other applications for $30 right now (includes a couple of good ones I've used, Fantastical and Ember). They also have a demo. I didn't like Aftershot's organizational setup overly much, but it did seem to do a good job with RAW. Worth a test drive at that price.
