As you can see, people who have Inova X5Ts really like them. They are very well made and, let's face it, they're the coolest looking light around. In addition, light output is okay.
I do believe that if you're either willing to spend more, or go with a light that doesn't look as good, you can find a light that will outperform the Inova. The E2e with KL1 will outperform the Inova as a light, and is also long enough for use as a pocket stick (at around $100+). A Maglite 2AA fitted with a Badboy 400 will also easily outperform the Inova as a light, and will work as a defensive pocket stick (at around $45 total for Maglite and Badboy module). If you're not worried about use as a palmstick, Arc LS with 123A module is less than half the size of the Inova and will outperform it as a light (at well over $100, although cheaper used and seconds abound).
The Inova isn't a bad choice. I personally would (and am) lean towards the Maglite 2AA fitted with a Badboy 400 and Kroll endswitch. But I keep getting drawn back to the Inova too ... I'm especially beginning to eye the blue one!
