I have bought and use Picture Windows Pro. Unfortunately digital photography is at the far end of my "things to do" list so I do not spend much time there. Everything that I have attempted seemed to work very well so far. Also there are many pdf's on the site that are quite helpful. I bought and use Vuescan with my Epson Expression for scanning 4x5 negs.
At this point and for my needs, Picture Windows Pro is hard to beat in the price per performance category.
I believe that Photoshop Elements is a testament to how good Picture Windows Pro really is and now Adoboe, is trying not to loose customers who are seeing the value of Picture Windows Pro. I also have sent Jonathan Sachs a few questions on his Q&A board and received very quick responses. A most helpful and patient person.
IMHO a great program for a great price.
