Lowes now carries Torin organizational products, so you may want to browse there, too.
Right now I'm using Ernst gripper wrench rails and the Kobalt trays for my sockets. Both work decently well enough. I also have a set of 3/8 impact sockets on the HF metal rails because I am out of room in my box for more trays. They aren't the most satisfactory solution but they work OK for now. I will be replacing them in the future.
I have a couple of the Ernst socket rails, too, the twist and lock feature is great.
I encourage you to consider some factors before you settle on a solution- such as, how deep are the drawers you will be using (shallower drawers are not satisfactory for standing up sockets), do you want the sockets in a grab and go package so that you can take them with you under a car or away from the tool box/cart (if you want portability, socket rails are the way to go IMHO), and how much money do you want to spend.
I do not recommend HF plastic rails (they ****), and against the Sort a Wrench wrench trays (too short for my wrenches)
