minimaglights are outdated, with breakable bulbs that burn out, short battery life and dim light.
This is the kind of thing that you can get today that uses a single AA, has a permanent bulb (LED), is regulated and burns up to 34 hours.

If you want something for the key chain or kit that is cheaper, uses a permanent LED and burns 21 hours on a single AAA battery, is regulated and is brighter than your minimaglite then this is the ticket.

Thank you for the links. I had already bookmarked that site from your previous posting. Those look like great upgrades.
