There was a professional fish/tanker/aquarium keeper/breeder person. He had tons of equipment for very good prices. He also had some cool out of the ordinary fish for sale. There was another guy selling - get this - complete 10g set ups, including the wrought iron stand for $35.
Then there was another guy selling a large variety of aquarium plants - I am not much of a plant person, but there seemed to be a good selection for VERY low prices.
Not many people showed up to buy so I left a couple of hours early. However, if you are in the area you should definately check out these swaps. They are open to the public. There is also a big swap meet put on by the Chicago folks... but used stuff doesn't sell as well there so new stuff is emphasized.
If you live in a large metropolitan area, check with your better lfs's and see if there are any aquarium societies/clubs to join in your area. They are fun!

P.S. Boy, it took me 3 hours this morning to bag the fish. Then all the unsold ones come home and have to get reacclimated, etc. It is MUCH easier to sell bunches to the lfs's. I'm still spending more than I make, but have been told that eventually this does turn around. If you want to breed fish to make money - dream on! But, if you enjoy doing daily water changes and watching little fishes grow up to start sparring with each other and getting all fiesty, then by all means start to breed them. I just love a tank full of the rams all flaring and struttin their stuff...
