Stealthboys... Where to find?

[Surf Solar]

I am currently at ca. half of the games progress.. And I need a stealthboy for a little quest. But the problem is - I cant find any stealthboys! The ones I found early game have been sold long ago... I checked the traders inventories, they are gone. I tried it in Primm, Novac, Goodsprings, the 188 Merchantpost, Gunrunners etc.. Nowhere is a Stealthboy. Do you guys have any idea where I could find one?

If you decide to fight rather than talk down the Nightkin in the REPCONN basement you'll end up with a few. I know for a fact there's one by the Nightkin corpse lying by the door as you enter. It's beside him, though – not 'on' his body.

I started finding stealth boys early on and have so far collected quite a few. even though I helped the Nightkin and made them leave REPCONN peacefully, simply looting the corpses and killing one or two on the way left me with plenty stealth boys. I haven't found any for sale so far however.

and I'm guessing there are plenty to be found in Black Mountain, although I haven't been there yet so don't take my word for it.
