I'll probably go for the T3 too. A clicky would be just a bit more convenient for me.
Though right now, there seems to be conflicting reports on how the T3 actually looks like. The pictures posted by Chris from Meridian Tactical suggests that the black X0 lookalike with knurling is actually a T2 with a 2 watter (?), while the one with the bigger head similar to the X03 is the T3 with the 3 watter. Some other websites/online stores are saying that the X0 lookalike is actually the T3. /ubbthreads/images/graemlins/confused.gif
Even Maxpedition, whom "At the behest of hand-held LED light manufacturer INOVA/Emissive Energy Corp." custom made the holsters for the T1 and T3, posted pics of the X0 lookalike, together with a smaller version (that is widely agree upon as the T1) on their website. There are also no official pictures of the T-series on Inova's website, so I'm not really sure which is which at this point.
