The Inovas are fine lights, but keep in mind that they use CR123A cells, and not AAs. The batteries are more expensive, and the lights are larger/heavier.
The Fenix line is definitely worth looking at. With an alkaline battery, the L1P has a typical discharge curve; bright at first, then dimming. It's "semi-regulated" with a DC-DC circuit, so the curve is better than basic direct-driven lights. With a lithium batter, you get a much flatter discharge curve, and one that lasts considerably longer. With a NiHM rechargable (check the FR link), the curve is also flatter with longer peak brightness, although shorter overall (but that's the point of having a rechargable, isn't it?...just charge it back up).
Check
here for a couple runtime graphs (lighthound is also a fantastic dealer).
If you don't mind a longer light with 2 batteries, you can use a L2P, which has a true regulation with a perfectly flat discharge until the batteries can't support it anymore. The L2P makes a Minimag look like a worthless hunkajunk.
Either Fenix will give you a tight, bright spot, with a wide, but fairly dim spill. The Inova T2 will have a larger spot, but still tight with little spill, and will likely outshine the Fenix. However, there's the batteries, and I always lean towards lights that can use rechargables for months of free lumens.
Another option would be to find a Target that carries the Inova Radiant series. These are less-expensive plastic versions, and there's a slightly-larger-than Minimag 2AA version. Long battery life, still pretty bright, and inexpensive.
