I prefer lithium rechargeable, since you can recharge them in your car if you are not around any power source. I got into buying Fenix as they have a good all around perfomance.
I really wish nudity was accepted in the U.S.A. Once I am home my clothes are off immediately, and it's the best feeling.
There are times I wish I could just walk outside to get the mail, or answer the door without any worries.
It depends on what you are looking for in a flashlight. From what I understand is HDS is well built, but they are not high output lights. I personally prefer high output for times I really need to light up an area.
If you don't need a super throwy lights, then look at Acebeam L16, Fenix PD36R, and I just ordered the Fenix PD40R V2. Acebeam & Fenix have been reliable lights for me.
There are so many more brands and lights out there that I would really consider before you make your decision. How far do you need it to throw, How bright do you need it, what size, etc. Also there are newer lights using the 21700 battery now.
I actually visited Surefire in Fountain Valley, CA., and I can tell you that Surefire does not care about their customers. They are too busy dealing with companies that buy in bulk.
