I went to Scales and must say that I was impressed with the conditions of the tanks. I would rate them above the other two in terms of conditions, but not sure they have quite the same selection as if you still make a circuit and hit a couple stores.
I got a nice tank bred female German Ram at Scales. House of Tropicals only had hormone induced males and Aquarium Depots tank was sick and pulled.
My tank is now stocked so, the trips will be fewer.
We used to hit the Aquarium Depot as it is on the way to the Russian food stores in Baltimore that my wife likes to hit. Now that we moved, House of Tropicals is on the way too. Scales was a bit out of the way, but worth it.
