Has anyone sent out their SRS unit to a company to get it reflashed and cleared as new? I've seen a few companies that do it in the US from anywhere from $50 to $150. Please let me know your experiences and what issues you had.

I was told I need a new SRS unit due to me hitting a curb a few months back and now getting a SRS light. It was attempted to be reset but still stays on. I am aware that I have to replace the seatbelt tensioner and am going to look into that.
