Darn! I hate it when a well-loved piece of cookware goes to the great stove in the sky. Even if it wasn't a such a much pan to begin with you get fond of them. For instance, I've got an aluminum 12" chicken fryer and an aluminum Windsor pan I got from Smart and Final which, in the greater scheme of pots and pans, are cheap Chinese junk. But they sure work for me.
Your Adcraft: Aluminum? Stainless with a sintered aluminum disk on the bottom?
Either way, there's nothing remarkable about Adcraft. As you said, it's neither Mauviel nor All-Clad. It's mid-grade pro cookware, and fairly fungible, and you should be able to find something suitable at any decent restaurant supply.
And really, there's nothing wrong with similar home cook stuff. "On sale" works just fine, and "deep discount" is even better.
That said, googling the search terms "adcraft cookware," got pages of hits. The first few I looked at it didn't have what I guess is the exact pan in question; but then I don't what the exact pan in question is either.
My best advice is that if you can't find it without too much trouble, get something else. Personally I tend to gravitate towards Vollrath and Lincoln, but there's nothing special about their mid level stuff either. Alla time same same.
