There are a few sellers without websites around and sometimes sell on http://aquabid.com
Collecting is far cheaper than buying, but buying is far easier than collecting in some cases. Stick to the smaller species and you'll be fine.
If you decide to purchase, check out Florida Flagfish, Golden topminnows, Least Killifish, and Bluefin Killifish. Many others depending on what your goal is. I haven't even mentioned a lot of cyprinids and darter species.
