Speed costs money. How fast do you want to go?
Reminds me of what my father in law said when it comes to cars:
Him: "You can have it either: FAST, CHEAP, or GOOD. PICK 2."
Me: Uh....Ill have it fast and good.
Him: It ain't cheap.
Me....um....Cheap and Fast?
Him: It won't be very good.
Me: Good and cheap then.
Him: It won't go fast.
