did all your lights go out? Not sure if you have multiple bulbs /ballasts. If you have any light left depending on your corals you might make it. might. I also would really try to find something that doesnt require shipping, maybe you can get expediated shipping on the ballast? Still wouldn't cost $100 I wouldnt think.
Good luck. You are in a spot I have nightmares about.
