I used the LD20 for many years, that's 180 lumens at max and I'd say worth the cost (c£50). I had a faulty tail cap switch on one which was annoying but believe that was a one off problem, the first one that I lost down a sewer was faultless.
I've got a TK75 now that's my standard walkabout torch, hasn't let me down yet. It's pricey but at 2600 lumens max it's more power than you'd need and lasts for ages at low power output.
