Where can I buy Mexican style chorizo?

[Ohio Dem]

When I was in college, there was a burrito place called La Bamba that had something they called "Mexican sausage," which I thought was awesome. I later learned that this sausage is called chorizo. I ordered some from a Spanish food website, and it wasn't the same. It was good, but it wasn't even close.

Then, recently, I had dinner at a local Mexican restaurant, and had some tacos filled with chorizo. Now THAT'S the stuff! It was SOOOO good. I've done Google searches for it, but I can only find recipes for it and links to Spanish food websites that sell it (not the same thing). I want the Mexican version.

Does anyone know where I can get my hands on some? I've considered asking the people at the Mexican place where they get theirs, but I don't really want twenty pounds of it, or however much a bulk order from a restaurant supply place might be. And I doubt the restaurant would sell me four or five pounds of it out of their stock (is that even legal?). Can anybody help me with this?
