My buddy banged a thin Venezualian with a pretty face and no tits for 280.
She wanted 600 originally and I negotiated on his behalf and talked her down. This was in Las Vegas, and 2-300 seems norm there if you don't mind a girl that is pretty attractive but has a few bruises on her knees from being thrown down by her pimp. So id say in terms of practical places to visit, USA/Las Vegas is pretty cheap.
