$250 isn't too bad. Mine was $500 and I had my stereo stolen. There was also some damage to the dash so I had to pay the entire $500 deductable. Then after my repairs were finished, I took the car to get a new stereo installed. The installers broke the piece of dash that was replaced (A $600 part, not including labor to install it) and they wouldn't take responsibility for it. Now I'm sitting with a half-assed mounted stereo and the cover doesn't close properly. I know this doesn't compare to what happened to you, but I hope it helps you feel a little bit better
Don't worry though. I'm sure it'll all work out in the end. And remember. Sh*t always happens now and then.
