We have used Amersham, NEN and Pierce kits (plus made our own).  Pierce
super-signal is, as they claim, considerably more sensitive than the
Amersham ECL or the older NEN.  NEN told me they can now match this with
their newer kits, but I have not tried them myself.  Pierce have a new
super signal Ultra (where do they come up with these names!!),
reportedly better again, we have ordered it, so watch this space for

Summary:  stick to pierce at present.  The signal lasts a lot longer (a
couple of hours).
