Find someone with >2300 mAh NiMH batteries to see how long
they last. You can get 2500 mAh AAs at Walmart now and with
a 15 minute charger (Energizer), you can recharge them quickly
and often

In the current (June 2006) issue of Popular Science, pg. 22, they did a test
of batteries in a digital camera. Since the requirements are not the same as
for a GPS, these results may not translate well, but they are interesting.
Conventional alkaline batteries: 533 shots
Duracell Powerpix (Nickel Oxy Hydroxide): 920 shots
Panasonic Oxyride (Nickel Oxy Hydroxide): 990 shots
Energizer e2 Lithium: 3,107 shots
Although the lithium batteries cost twice as much, they were obviously the
best deal.

I would take this a step further and look at life cycle cost.
Assume Alkaline battery = $1 each (533 shots)
NiMH battery = $3.50 each (900 shots assumed)
e2 Lithium battery = $3.50 each 3107 shots)
Also assume only one battery is needed.
Cost per shot then is:
Alkaline = $1.00/533 = 0.187 cents/shot
e2 Lithium = $3.50/3107 = 0.113 cents/shot
Yes the Lithium is better than alkaline.
But wait, we have examined the NiMh which is at first glance
$3.50/900 = 0.389 cents/shot but since it can be recharged
hundreds of times (let's be conservative and only use 300) then
we are at 0.389/300 = 0.0013 cents/shot. Even adding in the
charger cost makes the NiMh much better.
