Bob, if we look back at the thread: "Which chinese factories make various brushless motor brands?" - http://www.rcuniverse.com/forum/m_11426913/tm.htm; posts #20 to #25, I compared the prices for several motor brands.
I found that:

a. Turnigy SK3 motors are generally about 30% of the price of the matching and equivalent (and identical) same-size Hacker USA motor price.

b.Hyperion-Z motors purchasedfrom Aircraft World in Japan, arebetween one third and one half of the Hacker USA motor price.

c.OK Hobby Infinite motors are ~35% to 40% of Hacker USA price
Gens Ace motors are ~40% to 50% of Hacker USA price
LiPolice motors are ~50 to 60% of Hacker USA price
Pelikan Foxy motors are ~75% of Hacker USA price
Pilotage Nova-Line motors (mostly in Russia & Ukraine) are ~same price as Hacker USA.

d. Extreme Flight Torque motors are about same price as Hacker USA, occasionally slightly more.
