Grrr. Roommates. They're a pita mostly, unless they pay the bulk of the rent.
Sorry to hear about it. If you're just going to repaint, check out eBay for a used panel. There's something to be said for the quality of the OE plastic, and if you can get a good deal on eBay....
I'm needing a left mid, myself (mine's missing a small corner where it cracked), and it's rare as all hell. I'm holding out for a NOS, I know there's one out there somewhere and it will be mine when I find it...
I have lots of patience.
Good luck.
