wow. this is the first "help me" thread I've seen where the OP suggests a really good light to start (that includes my threads)
The L1D Q5 is definitely in the top 3 unmodded AAs prefered on this forum, and some like it best.
For $30 more you can get the Nitecore Defender Infinity. It is not necessarily better, just different. It has two adjustable modes and a well-hidden strobe feature. It is better as a tactical light because 1) body is kurled, providing better grip, and 2) it has a forward clicky tail switch (it has momentary-on in any mode). It certainly looks more solid than the Fenix, but actual reliability and quality is about on par with Fenix.
Also at $80 you can get a JETBeam JET-I PRO. I don't recomment this light, based on all the reviews I have read. It has amazingly inefficient medium and low modes, is a bit larger, and overall seems to be a bit quirky. The reason I mention it is that it is currently the brightest 1xAA light out, with barely more overall light, but around twice the throw, of its competition. It is said to be build very nicely, with some fancy touches (gold-plated spring, saphire crystal lens).
The NDI and Fenix seem about evenly balanced, so you should try to read some more about both before deciding between the two. If you buy the Fenix, Fenix Store is a great place to buy it, especially with the CPF discount. There are detailed reviews of the JETBeam and NDI here:

Just an end note: there is also a flashlight called the Olight T15 Q5. It is very similar to the Fenix, but puts out a tiny bit less light for a slighter shorter amount of time in all modes. But some says its build quality is worth the difference.
