Mike, all: has anyone found the stock number at B&H for the Gel Snap 
and and IR filter? A search on site reveals some 10 "sets" of filters 
with the gel snap holder, but nothing that might be used in IR 
photography. This is a good alternative to pricey glass filters which 
will be used only rarely; much obliged, Mike.
