You can loot them from The Glow.
Far too expensive - you use all that Rad-Away, take all that time and maybe get nothing. I just went there with a LP 300 guy and could only open 2 safes the entire time we were there. Yes, i had lockpicks. No EC ammo, no Stealth-Boys, no motion sensor. So either someone put special locks on those, or we found a bug, or LP 325 just isn't good enough anymore.
