I haven't tried most of the new DealExtreme flashlights, and I'm sure a lot of them will be great bang for the buck, possibly better than what Fenix L2Ds offer.

However, I do think a big consideration that often isn't mentioned is the high build consistency of the Fenix lights. They're super reliable, built well, and if you do manage to get a defective one, you can get a new one within a week from Fenix. Dealxtreme is known to have the more than occasional oddly shaped part or thread that may or may not give you headache down the road.

For something mission critical like consistent night riding, I'm more than happy to pay a small premium for the quality and consistency that Fenix seems to have offered to the hordes of users on these forums.
