At the risk of sounding like an old school hold back, I gotta weigh in on laminate flooring. I have installed thousands of square feet of various wood and laminate flooring. Even though the new laminates tout the hard durable finishes and long warranties, the common weakness of laminate is that it is a picture of wood on some type of paper or synthetic base. When a sharp heavy object tears away the paper thin "wood" picture off the top, the warranty covers that one piece of flooring, not the entire floor or the labor to replace it, which is almost impossible for a single piece in the field of the floor.
The other major concern I have with most laminates is the reaction to water in areas like a kitchen or bathroom. Admittedly, I have not checked out the particular items you linked to, but in general, almost all laminates will swell and bubble at the mere site of water, and the damage is irreversible. Be absolutely sure the product you select will perform as promised if accidentally covered with water from a leaking pipe or an overflowing sink. Ask for a small sample and leave it in a sink of water for half an hour and see it there is a reaction.
I will not supply or install laminates, especially when there are a lot of good real hardwood click lock engineered flooring alternatives out there at the same or lower cost. A good engineered flooring material will have a 1/4" to 3/8" 3 ply plywood backer and a 3/16" real hardwood veneer top, that can be sanded and refinished if necessary. Engineered products are very temperature and humidity stable, feel and sound a lot more solid under foot and can be cared for as you would any real hardwood floor. I recently installed 300 sq ft of a Shaw engineered product, 7 foot long X 7 1/2" wide snap/clink lock panels. Quality was excellent and went down extremely fast. Price was under $4.00 a sq ft.! Not pushing Shaw products, but I was reasonably impressed and I am a tough sell.
The other piece of advise I'd give you is to check some of your local flooring liquidators that sell retail as well as wholesale. You may find a bargain on something of much better quality at a very reasonable price. Even though I drop apx $80,000 a year at Lowe's and maybe $10,000 at Home Depot, I never buy flooring there. I always get better product, better advise and cheaper prices at my local flooring warehouse.
