I TA'd a molecular biology lab 4 years ago when I was a U of Minnesota. 
The class used BMB's Genius Kit (digoxigenin label and CSPD detection) to
do a Drosophila genomic Southern blot for RFLP mapping.  It worked quite
well.  However, there MIGHT be a problem with plaque lifts on
nitrocellulose (instead of nylon) membranes.  I now successfully use
nitrocellulose membranes but I switched to the anti-DIG-Peroxidase
antibody and luminol detection instead of anti-DIG-AP and CDP-Star.  I
cannot comment on whether it would have worked with anti-DIG-AP nor can I
comment on Northern blots since I have never tried them with the Genius

Good Luck,
