The best light I've heard of for under a hundred dollars is the magic shine P-7. It'll run you about $80-90 depending on the vendor. There are a couple of forums about this light over in the electronics forum.

FWIW, those target lights are just "be seen lights" there only maybe 55 lumens or less, the magic shine is rated at 900 lumens, but I've heard it's more like 600.
