For that price range you are probably looking for a 7mm product. Don't go less than 7mm. Lowes does carry a 6mm and 5mm from time to time. They break as you install them they are so cheap. I prefer an 8mm or better myself because you get less cracking and hollow sounds with a thicker product. Yes the pad with the taped edges does provide an adequate moisture barrier. As for brand, stay away from anything made by Kronotex, that includes Formica brand. Quickstep is one of the easiest to install. Mannington, Wilsonart, Shaw, and Armstrong are all good easy to find brands. Yes you can do it all yourself with some planning and research ahead of time. The hardest part is usually dealing with installation around door frames.
