Faction in ShadowheavenFollow

The vendors in stunty town don't seem to sell to anyone except for other stunties. Since I think about a Bazaar mule that will also do my shopping for the TS items I cant get around my Elvish towns (and my char is on 4 skills simultamously)I wonder if I take a gnome or dwarf then everyone ELSE will probably not sell to me? Or will a plain human with decent CHA suffice?

Some expirience(!) ;-) based advice will be greatly appreciated.
