One of the Daughters at my table said that another of their sorority had actually made the haggis, so it wasn't imported/canned. So I can attest that she makes pretty good haggis... but as for anything else in the states, I'm as ignorant as you I've heard um... Caledonia Kitchen? makes a decent canned bit that you can get here, but I'm not all that sure I want to try it ;)
