Non-radioactive Labelling Kits

[IXK3 at psuvm.psu.edu]

In my lab we are thinking of switching over to non-radioactive
means of detecting our Southern blots.  Virtually every
supplier out there these days has some kind of kit to do this,
but never having done this sort of thing before, I am not
exactly sure of their relative merits.

Has anyone had any particularily good or bad experiences with
any of the random-primer kits for non-radioactive labelling that
are easily available?  Or are they all as equally sensitive, reliable,
and convenient as one another?
