Avoid Armstrong and any of their subsidiaries (Bruce/Swiftlock). They use a lock and fold system which is complete garbage, it doesn't lock meaning you will have flooring pop up, separate and even chip and it's noisy.

There is quite a bit about it on this forum; http://ths.gardenweb.com/forums/load/flooring/msg0721340413169.html.

I had mine completely removed.

It's Not a lock and fold system or a glue down type....it's nail down solid 3/4" hickory. I went to a client of my husband over the weekend. And She LOVES her and I loved the look.

Oops, thought it was their laminate.
