before you rush to spend your money on the Inova T3, try to use one of the newer LED flashlights - maybe borrow one from a friend?
I just got my Lumapower F1 which uses the SSC P4. It is not intended to be a very powerful light, only uses a 1xAA battery (in fact so far I only used a stock alkaline primary) yet it is a beautiful beam. And extremely useful indoors.
I also got the Lumapower M1 and am sure it will do much better than the T3 based on the specs. Big throw, nice useful spill, also very rugged with a crenelated (tactical) bezel, HA-III anodizing, etc., etc. And on runtime it will just go on much longer than the T3.
Then I could go on about the L1D CE...(which I got while awaiting the 2xAA tubes to become available...)...
Really, these new lights are amazing, read flashlightreviews.com on the L2D CE (and similar lights) and you'll see what I mean.
Especially if money is tight, make sure you spend it wisely! Why reward companies that are behind the times with NEW products? If we reward the companies that forge ahead with the new technology, then the Inova's of the world will be forced to catch up with them, and then we'll all have an even better choice - get the Inova because you like the construction and the looks, but ALSO get it with the newest available technology, and at competitive prices!
