I always liked Novak Brushed ESCs, they are definitely worth looking into. But if for some reason that does not work out for you, you can check out Ebay. Many good deals on brushed ESCs there. Or any of the Duratrax Intellispeed series are good low cost options. If you find something you really want but it is out of your price range, and you consider spending more, be careful as for not much more you can have a decent brushless system that will last for years instead of runs. A few common mis-conceptions are that brushless is expensive and that it is way more powerful. For right around $70 you could pick up a EZRun brushless that would be similar power and speed as stock, but it will last for many years if treated properly.
