Mucke's is a local Connecticut processor which makes great natural casing franks. But they also make a pretty decent kielbasa link. While not as authentic a Polish sausage as the truly real thing (such as Enfield's own Janik brand) Mucke's kielbasa dogs have a good balance of spices, a touch of smokiness, and are a heartily-textured link that stands up well to grilling. They make a nice change of pace from standard dogs. I highly recommend them.
