Thanks for all you kind comments. Yes I did play around with all the sliders- so this is not right out of the box. Am writing a tutorial about it and I have to say it works very nicely indeed. This "hdr" was made from one single shot. I don't like over-cooked hdr shots, but than this is personal taste. I am evaluating Photomatix against Nik's hdr software at the moment. It definitely wins over Photoshops HDR capabilities.
