I want to try the HW with the new ESC, but the warranty service worries me. When my RS broke down, tekin replaced it, no questions asked. Tekin is also based in the US, so the shipping was fast and cheap. HW, on the other hand, aren't they based in China? It'll take weeks and a good amount of money to ship it back and forth?

There's no doubt that the two esc are matched evenly. But for me, warranty convenience is a high priority on my list.
