The Novaks are great ESCs, but the Mamaba Max is hard to beat. You can get a new one for almost the price of a used Novak. The Mamba Max probably has one of the better programing interfaces and it does brushless/brushed, and sensor less motors. So you are covered for every type of motor, and I am pretty sure there is no limit on any type. I saw one here on our buy/sell section for 95 I think. I see them regularly for less then 100$, maybe not the absolute cheapest, but I think the best bargain and value for your money!
