GARY, YOUR CORRECT ON THE HALON STATEMENT, MY GUY WHO REFILLS OUR SHOP EXT SAID A REPLACEMENT CALLED HALLOTRON(?) IS ON THE WAY. APPARENTLY HALON ISN'T MEETING THE EPA'S GUIDELINES THESE DAYS. WILL BE INTERESTING WHAT THE AIRFORCE AND GUARD BASES DO? I SAY IF YOU HAVE A HALON ONE BE STINGY WITH IT OR GET CO2. SCOTT
