I created my first vault, my first lunch box netted me a lvl 44 star paladin cross (comes with B.A. armor and weapon), some other weapon and a ton of caps.

Not too long after I started, I had like 18 dwellers, and got raided, my star paladin was out in the wasteland so hardly any resistance...they killed nearly everyone. I was frustrated and didn't realize the "ramifications" of just deleting all of the corpses. I was down to like 3 people. Lucky me, I had a male and female and started them a-breedin'..I have had 1 straggler come in, but I'm up to 19 with one imminent birth.

In the meantime, I figured that I wouldn't abandon all hope and delete the vault. I started a second vault and got a mid level ninja dude. That vault is doing "ok"...but not great, my first one is REALLY thriving though.
