Cheapest one I found was at Wal Fart for the race car. Seems to be holding up decent as it gets thrashed pretty good. Only died once from letting the fans go while the car was off to cool down. It has probably had 500 starts over 200 miles. For $39.99 it can't be beaten plus it has a 24 hour warranty in most areas as its hard not to find a Wal Fart around ya. You just need to duck the bullets as you go in.
