I just looked at the picture he sent me. It does have a barb fitting on the regulator after the shut off valve.
I ended up just buying the keg, a set of replacement of rings, and some keg lube for $62 and some change. I got to hand pick my keg which was nice.
Brought it back home. Still pressurized as they stated. Cleaned the outside up. A couple dents but nothing excessive. One thing I didn't like was that the inlet tube is plastic. I think I can buy a new stainless one. Overall the inside was clean but I'm going to soak it in pbw and clean the lid and parts as well.
