I use 'Dynamic Photo HDR' I find it very good and easy to use. You can create HDR from a single RAW with three modified versions of exposure in CS3 and DPH, but it doesn't work quite as well as having three seperate RAWs shot by the camera. I think the reason is if you use one RAW you are tweaking it to pretend the camera captured at a higher and lower exposure. There is a lot of data in a RAW, but when I tried it in comparison it wasn't quite as good as three camera RAWs. It does work pretty well with one RAW though. See my test file I did of my house below. You can see more detail in the darker areas of the three camera RAW version.
