The best place to go--and there are lots of them out there--are professional fire-supply houses, that supply equipment to fire, rescue and ambulance corps and companies. You'll have a huge choice, better prices, and lots of good, professional advice. Just look in the Yellow Pages.

As I remember--it was awhile ago--the local company (we use them for the volunteer ambulance corps I'm a member of) turned me off on Halon when I told them what I wanted the extinguisher for, though I can't remember the reason. Might have been duration of the charge.
