I personally LOVE Lego Power Functions, but recognize that the use of motors may take away from some of the set's complexity and add A LOT to the price of the set. Let's assume that the Technic Challenge's winning entry must have a maximum Price Point of USD $199.99 (the same price as the current 9398 4x4 Crawler). The 9398's three motors are worth USD $27x2 + $36.39 = $90.39 (45% of the total cost of the set) -- recall that on this Eurobricks post, Crtlego wrote,
"And now that we have some ID numbers; I was able to call Lego from the U.S....
L-Motor (6000564) - $27 - Not Available
Servo-Motor (6000566) - $36.89 - Not Available"
I did not include the cost of the 8881 PF Battery Box (USD $6.99) or the 8884 PF v2 Receiver (USD $14.99), which add an additional $21.98 to the $90.39 cost for the 3 motors. The total cost of "motorizing" the 9398 4x4 Crawler is USD $21.98+$90.39 = USD $112.37 (56% of the total cost of the 9398 set)!
