That area is huge for MFK as well as the Capital Cichlid Association if my memory serves me right; you'd be able to move those aquariums fast if you have them up for sale at a reasonable price. Just be sure to factor in your time, effort, and transportation fees when you price them out, and go from there; a $1-2 per gallon isn't a bad price while it's still going to make you a fair bit of money. Regardless of how much you sell them for, I'd hook up the lady that's giving them to you with some of the money, too.
