I am thinking somewhere in the $25-$50 range. I don't really need outrageous throw considering I will have a larger light on me. Most likely a loaner but should I invest in a smaller light such as quark mini aa and slap that on a headband?
hmm, this is kind of tough because it sounds like you're starting from square 1. it sounds like you don't use a headlamp much, and don't plan on using one extensively going forward.
if you are mainly a handheld user and have only used crappy headlamps so far, let me say that a good headlamp can really change the way you look at individual outdoor lighting. having a floody on your head with a smooth wide beam is a real game changer IMO when you're working with your hands.
for a AA format, the Zebra floodies seem to be the best suited for the purpose, but they're a little out of your requested price range and i don't think you'd want to use a Zebra as a loaner. they're too nice, and maybe a bit delicate, for that.
you might want to look at the Petzl Pixa 1. it's not that bright, but it should have a smooth floody beam that, i think, will work for you. it's also waterproof and pretty rugged. it takes 2xAA, it's regulated, and the price is right. i think the price and rugged build make it a good loaner. it is a little bulky though.
i would avoid the Fenix headband unless you want it for wearing 2AA clikies on your head. i used to have one, and i didn't like it. i wear glasses, and shorter flashlights would shine into my glasses and cause a lot of glare. operating the twisty with the headband was awkward too. if you really want to go the headband with hand held route, i'd try the Nitecore headband instead. the Nitecore offers more mounting options, and you can just slip the light in and out as you please, so that makes it a little more versatile.
+1. i also recommend looking over Bolster's "
To Consider Before You Purchase a Headlamp" thread.
