I discovered the program call Enfuse and I am really impressed with what you can do with it in conjuction with SPP4. What you do is export two images from one X3F file, one that is dark and one that is light. Then you use Enfuse to put them together. You get the best of the highlights and shadows without the funny look the the X3 slider can give. This is a SD14 400 ISO shot using this method.
