I have one of these

Very bright...long thro...small...well built...can be held in mouth....and has a clip to fasten it to the beak of a ballcap to use as a headlamp.
If you want a hands on look at one RadioShack (or whatever they call themselves in Canada)has them, sold under their own name, for $69
I've seen them online for $29US but ordered from these guys being in Canada and didn't want the customs hassle. Shop around.
I also ordered up 4 rechargeable batteries and charger for around $25 (forget where tho) Rechargeable CR123a batteries come in 2 voltages...3.2v and 3.6v...I chose the higher (gives an even brighter beam than the regular 3.2v)Being a single cell light the added voltage is not an issue (I believe the bulb can handle 4.2v) I get about 40 mins/battery before the brightness steps down.
my 2cents (for what it's worth)
