Fire extinguisher question

Hi All,

I had a small engine fire yesterday.
Nothing really serious, just primed too much and whoomp.
Damage, 1 hose costing 22,50 euro, 1 empty extinguisher and a dented
ego.
Now i have the problem about replacing the extinguisher.
The old one contained Halon, but this stuff is prohibited in Europe
from januari
1st 2004.
I had a look at CO2 but these things are really expensive (150,-
euro).
The ones containing powder do more harm then good, the engine has to
be taken apart for inspection after using one of those.
Has anybody other suggestions?

Thanks in advance,
Kees.
