I think Pergo is a great product. Easy to install, and practically indestrucable. Easy to clean and keep clean. One exception; water can get into the joints and cause it to swell permanently. I would use waterproof glue in installation.
Walk on a Pergo floor if you get a chance. It doesn't "feel" or "sound" like a wood floor. That really did not bother us, but some people it might.
