Thanks for your all inputs. It really helps me to make decision on the canister light.
My option is only either Halcyon or Salvo.
I didn't know that Barry has a workmate, Duane.....So, how about Duane?
He is also a good expert on the light. He isn't picky on the customer service?
Based on my experience with Halcyon customer service, it has been very good. They were very informative and responsive to my newbie inquiries (It looks like they know the business how to handle the new customers. You know, how to meet the new customer's need is another key factor for the succssful business). So, that is the reason why I got many "H" dive gears including four BP/W. But, I was occationally told some complaints about their warranty and customer services. The canister light is the most service demanded item as I observed...
