The weird thing is, I don't see that much of a price difference between high-end "domestic" parmesan cheeses and the proper Parmigiano-Reggiano. The Saravecchio Parmesan (that's the Wisconsin domestic you're referring to, I assume) is about $17.99/lb, and the real, imported stuff is about $20/lb--even cheaper at places like Costco. So why not just get the real thing?
