I just checked. Adobe went to the subscription model 2011 - 12. I used it for one year, as I was working 0.8 FTE at that time. Realised I never used the photoshop aspect of it, and had PSE if I needed/wanted cloning or localized sharpening. Reverted to the standalone Lr which I've used ever since. So that makes it cheap software. DxO PL5 has the potential to be equally cheap for me if I don't need to upgrade.
