There's a guy out in Macomb and another guy in Pinckney who breed. Both list on craigslist I believe. You can get some nice fish at decent price from local breeders usually. PM me if you need more information and 'll try to find their posts.
Personally after buying from the LFS, I'd stick with either Kenny's Discus, or Discus Hans, maybe even Chicago Discus. You'll get better and bigger for the money compared to LFS.
