Eugene,
I wasn't putting the Arc light down, just pointing out an inexpensive alternative. The Garrity light I described is a quality, well made light AFAICT. Come battery replacement time, it is a question of do I replace the battery or just replace the light.
Sorry to hear about your wife. What did she do to have to pay the ultimate sacrifice? <img src="/images/graemlins/grin.gif" alt="" />
