Thanks for the help. It seems that the shinko 80/80-16 listed on amazon for a great price is actually tubeless. It says on Amazon it needs a tube, but the people who have bought it say that when it arrives, it says tubeless on the tire. They have all installed it tubeless, and are happy.
So I am going ahead and will order both of my tires, front and back, on Amazon. The price is hard to beat.
