Michael,
Not everyone has the time or hobby motivation to put together a complete B.O.B. for themselves or family. If you go the prefab-BOB route, I would still recommend a bit of post purchase customization to fit your personal needs.
Being a good Utah boy, you are lucky to be in the same state as two excellent preparedness companies.
Emergency Essentials-
http://beprepared.com/and
Nitro-Pak
http://www.nitro-pak.com/Both companies provide pre-assembled survival kits. The 72 hour kits are a good start.
I would prefer that someone purchase a less than ideal BOB than to have nothing because they were unable to put together a BOB before a crisis.
Good luck, TR
