I have seen flooring for as little as .99 per square foot,
but you know what they say about getting what you pay for.
If you hit a medium, you would pay about $3 sqft and you can probably add $2-$3 for installation.
We got PERGO in our last house and we loved it; it was easy to keep clean, didn't dent, and showed no wear after 4 years. I highly recommend.
The story goes that Europeans would put Pergo in their rental, and take it with them when they moved.
