Headlamps for runners.

Anyone got any experience with running with headlamps?   Figure if I'm going to keep doing this in the fall I need some light.  I saw some good reviews for the Black Diamond Sprinter but need to savvy advice before I go out and buy one.

This is how I roll... Delivers 100 Lumens!!!!! Lights up the forest at night, I use this for all my Ultras and training runs in the dark. amazon has these for $70 ish    

Good idea. I find even when I run on the sidewalk with street lights there are parts of the street that aren't well lit enough for me. I don't like running if I can't see where my feet are landing.

I just have a really cheap one I got at REI or Target. It's okay but Dan's would be better.

I use a cheap one I got from Target that clips on my baseball cap.  I think it was like $10.
