The main advantage of the battery pack will be running time. So I suppose it depends on how much you want to use it.
I've looked around and there are loads of torches running the same emitter with 2 AA's which should get up to decent outputs, they're also half the money of that one above.
Personally I'll be going for one of those with a 2 fish holder. I won't need more than an hours usage at a time anyway.

Due to heat, optics, cooling, and a host of other issues there is no way you are going to get 1000 lumens out of a single XML light. The ad for 1800 lumens is a flat out lie. You aren't even going to get half of that coming out the front of your light.
