Trust me mcnair55, not buying a D10 because a couple members had issues is a serious mistake on your part. If you review all the D10 threads on this site (
here is a good place to start) you'll find it's a forum favorite that's tried, tested and true. I've EDC'd a D10 Tribute every single day since I got it and I can't praise it's operation enough. Out of dozens of 1xAA lights I own, it's the only one I leave the house with every single day.
That said, the LD10 is what I carried before I had my D10 and it's a great little light. The soft-click UI is a pleasure to use, the threading in the head/tail is smooth and strong, and the light feels sturdy in your hands. I expect it'd survive a fall better than my D10. It has a good beam tint and is plenty bright. I hate the clip - it's the worst of any light I own (in my opinion).
Having owned, carried and used both extensively, the D10 is my recommendation.
