-The reason why I'm reluctant to get, say, a MS 900, is if I commit all of my financial resources to just the one system- what happens when one component decides to quit? If I utilize a dual flashlight set-up, then if one fails, I still have one that is operational (hopefully) that should get me to where I'm going in one piece.

It's a very good idea to have a backup light. I use the shiningbeam light to see by, and a ~$12 light from Target as a flasher to be seen. If for some horrible reason my flashlight breaks, the Target light would be enough to get home by. It would be slow going, but at least I wont have to walk by the light of my keychain light.
