I finished putting down the Ikea laminate this weekend. It was fairily easy to install but you have to be very gentle when bringing the edges together or they will splinter and the laminate (sticker) will split. It looks pretty good but you can really make out the seams when there is a glare from sunlight. Some of the seams are uneven by enough that you can feel it in socks but that may be because I hit the two peices together too hard when installing. It's a fine line between too hard and not moving the pieces together at all. I would estimate that the more expensive stuff would look better and go together easier.
I was able to do a 16 x 16 room from carpet pad rip out, to having the floor laid in about 10 hours. It's easily a one man job but it would go much quicker with one person cutting and the other laying and staging.
Good luck to any who attempt, send me a message if you have any questions or want more detail.
