None of the stations in Rhamus sell the Hornet MkII

I could understand the Mining/research station not selling it... but the Barracks? It has the base and MkIII... Take away one of the Atlas' and give the Barracks a MkII

why do you want a mkii hornet so bad?

It's the cargo variant, good for mining for people like me with no mining or trade license. Anyways, nothing besides the incredibly basic things should be available everywhere. Try taking one from Initros and selling it there, you'll probably get a load of credits.

ShankTank... I've done that. Don't remember how much I made from it, but it didn't seem particularly worth the trouble. What you might try is loading up with a trade guild mission to double the benefit.

It would be nice, however, if the station would start selling them after hauling a few over.

I suppose that's part of the new dynamic economy that is Coming Soon.
