I have read through this forum and understand that the cheaper laminates are not as high quality as the top end. One thing I am confused about is the ratings.. if a floor is rated AC3, doesnt that mean that it is just as wear-resistant as another AC3 floor (isn't this a third-party standard)? In other words, if I see a floor for say $1.50 sqft vs 2.50, and both are AC3.. what is the difference from a wear perspective? Both are 8mm thick and the cheaper actually has a longer warranty? I don't necessarily want the "Lexus" of laminate floors, but I dont want trash either. I appreciate your advice!
