Also, if you're ever in Stevens Point, Ski's Meats makes a pretty delicious bratwurst (and their smoked summer sausage is excellent).
And let me second the recommendation for Ski's. Bought a couple tri-tips there this spring, a skirt steak last time I was there. Great brats and sausages. I really like this place. Good fish too.
I don't know about chorizo, but the butcher shop at Jennifer St. Market has a good variety. Also, the "mercado" on Monona Dr. at Frostwoods has a pretty decent and "authentic" meat counter.
