Huffy (some bikes were OK, but none of the road bikes that I know of) , Murray, Sears (IMHO), Kent, Chiorda.... As you can see from the other comments...materials, components, workmanship, condition and fit are the major points to focus on. Don't forget you can look up bikes by manufacturer and model as well as old catalogs online, many of which can provide you with specs and placement within the product line. Don't forget, if you buy a bike and ride it and decide you don't like it (not a good fit, don't like the "feel" of the ride) ... it is easy to resell it. You may have to try a few bikes before you find one you really like. This is alot easier to do with $10 to $75 garage sale C&V finds then with a $4,500 bike from an LBS.
