quite. the price is at least 50% higher, but i can go out right this 
minute and buy a 5lb or a 10lb halon bottle without any trouble -- if 
i'm willing to pay the price.

there isn't really a good drop in replacement for Halon. FM100 is 
banned in the SCCA because it is somewhat toxic. AFFF is a foaming 
agent rather than a gas, and requires different nozzles and different 
nozzle placement to work properly. there's a 3M system that i've not 
seen in any cars yet (i'm an SCCA tech inspector and look at a _lot_ 
of fire system installations during the course of a year.)
