Muffler flange repairable?

[Pinchy The Great]

I just took off my muffler clamp and noticed part of the muffler flange broke off, as shown in attached image. I was about to replace my manifold seal when taking this off - maybe this was the source of the noise to begin with. I see a new muffler will cost me $155, which I can pick up locally.. I'm wondering if it's worth buying a new muffler setup, or if this is something worth repairing for much cheaper? I was thinking of taking it to a mechanic and seeing if they can weld/repair it, but that might end up costing more than I think. Or maybe some repair kits I can pick up at AutoZone might do the trick - then again, the last muffler I had before this had plenty of issues because of a bad flange and would fall off all the time, when I got this one it was problem free until now (about 10 years old)

Any advice from somebody who has dealt with this problem before?
