A best bet is the Hot Wheels 3-Lane Super Speedway for $65.99 before the above discount, $49.49 after. With free shipping, that's the lowest total price we could find by $33. It features lane changers that facilitate crashes, speed boosters to make the crashes better, and includes 10 Hot Wheels vehicles to give you something to crash together. It all sounds very violent, in an awesome way. Kids'll love it.
