If I lost everything I'd be devastated as whilst I haven't had my figures since I was a kid several of them have sentimental attachment for various reasons which could never be replaced.

I probably wouldn't replace my entire collection but like Jazzcomp be more selective and probably only replace a few choice pieces... ones that I can rebuild memories with or that just make me genuinely smile - like Ultimetal Prime - If I'm having a bad day all I have to do is walk past that figure and he brings a smile to my face.
