It's as good as any and I think I considered it back when I bought the D40A, as well as the EagleTac 3xAA light and the NiteCore EA4.
I'm pretty easy going with my lights and now don't pay much for them, kind of more in the 'budget' arena, at $50, or less.
At that price, buy one and see, as you're not out a lot of cash and you can always sell it off down the road and recoup some of your money.
I didn't need another D40A, but I like the light and it works on AAs, which are ubiquitous. I could have gotten mine back, but at $35 shipped, it's a no brainer for medium distances.
Good luck. I'm waiting on my NW D40A now, but I don't know of the Feds gave the post office off today, lol!
