i8 am building one, paul.
i found a cheapie ray-o-vac kid's 2xaa headlamp (aka optronics, i think) for $6. it appears to be pretty nicely made, with a clicky on the side, and decent strap. it uses o-rings throughout. plenty of room to cram everything inside.
im placing a luxeon III driven by a micropuck in it, and using a switch w/resistor to create a low beam.
i dont believe heatsinking will be a concern, since i have used the same combo in 2 angleheads with difficulty.
the star will be bolted to a small computer heatsink.
oh...and i can choose my optic.
i like aa bats as well, especially with step-up electronics. this allows me to use whatever i like: alkie, lithium, rechargeable, whatever.
just food for thought.

bob, I've got a kids ray-o-vac $6 wally spl sitting right here thinking of the same thing.
but I'm waiting for Lamda's new bi-pin led for $10. 35+ hours of runtime at brightness better than TNC N-cell.
should require almost no mod to install. I just did the $12 version of same light by dropping a TWOK star.
the bi-pin led will drop right in there too.
ray-o-vac ez headlamp mod
