Backward power leads!

[highpowerhobby]

I plugged in my battery leads backwards,heard a good snap and nothing works! How fried is it? Is it worth getting fixed...4 weeks of turnaround,$70.00 plus postage? I am pissed off....never even got to run it once! I am surpirsed there is no polarity protection. I did not notice the + and - connection designation on the esc input.....one of the dumber things I have done.
