In my opinion the only two to consider are Tekin and Hobbywing. Tekin has great customer service, and the product is reliable as well as competitive with anything on the market. The Hobbywing Xtreme Stock ESC is much cheaper and offers the same performance, and I think it is a bit smoother. The reliability is as good or better than anything else you can find, but customer service is lacking in the U.S. because they do come from China. For me, both of these are so reliable that customer service is not a major factor in my decision.
