There's the Peak Eiger and Peak Eiger X, and the TnC Nano Lux and TnC Micro Lux Turbo offered at RMSK. They're worth considering too. Some use 10440's for increased output. Some of their lights are available in aluminum, stainless, nickel silver, copper, brass, and titanium. I have several of their copper versions and they're great. Built like a tank. Prices for the above range from $40 to over $150 mainly depending on the metal selected.
As the others use a 10440 lithium ion AAA size battery, unless the intended user is familiar with lithium ion cells the regular Eiger would be fine as it can use both AAA and 10440 batteries. Prices range from $40 for the aluminum non-QTC model to $95 for the copper. I'd spend the extra $10 and get the QTC HAIII version. For a little more the stainless steel QTC model for $70 would be very nice.
Only thing is the shipping is a bit high and they only ship UPS. But they have great customer service. Bob Kastan is the person I usually deal with and he's always on the ball and reachable by email.
Str8stroke already posted a nice little lineup to get you started. Here's HKJ's review of some more AAA lights:

The review is from 2009 so many are no longer offered and others were limited editions (like the Photon Fanatic Little Killer) but it'll give you some idea of the extent of the playing field.
