Does anyone have a line on where to purchase the "old style" round Futaba/Hitec adapter cord to use with the sims? The round trainer connector on one end and the mono 3.5 mm jack on the other? I can't seem to find these on dealer sites anymore... e.g., TowerHobbies & OhioModelProducts...

Tower only shows the newer style Futaba square adapter and OMP shows a $40 USB job... I was hoping for something more like $5 or else I may just butcher a trainer cord!
