Hi Ninegunner, I have bought a few items from eCop, but no Surefire items. The items I did buy were authentic, and I had one item that had a defect and their customer service was quick to respond and treated me well. They have good prices, but you will notice the steeply discounted items are usually no longer in production. The newest Surefire items seem to be within a reasonable range.
There is another eBay seller that advertises Surefire weapon mount lights for $59. List price $300. When you look at the photos, the only item that actually has the word "Surefire" on it is an orange packing box that is always the last photo on the site. That one is easy to avoid.
I also recommend only buying Surefire batteries directly from Surefire-there are so many counterfeit batteries out there, and if using a two or three cell light, the risk for turning your light into a pipe bomb is real. Granted, a very low probability, but if you can buy authentic Surefire batteries for less than $2 apiece from Surefire, why take the chance. If there are other Flashaholics near you, I recommend buying in lots of 72 or greater and splitting the cost. With a 10 year shelf life it's a good investment.
