I got the three programs too and I process everything in CCDStack. I just love its DDP implementation and data rejection process. I have to admit though that CCDIS has let me down in numerous occasions. It seems to rely on the previous star pattern and works its way up from one sub to the other incrementally but if one sub happens to be way out of alignment from the previous one then it fails miserably and all subsequent subs will not align. Having said that some time re-ordering the subs or not including the problem sub in the alignment process resolves the problem. Registar on the other hand will align pretty much anything to anything even if the resolution is different and it will also warp the pictures to match, which CCDIS doesn't do. The latter only translate, scale or rotate.

Also if you already own CCDInspector, that installs the CCDIS plugin into CCDStack.
US$290 for CCDStack and CCDIS, $380 for CCDStack and CCDInspector, $90 for the CCDIS plugin alone.
US$149 for Registar.
Horses for courses, but if you already own CCDStack or CCDInspector, buying the other gets you so much more than a star registration algorithm.
Cheers
