we did mohawk laminate in our basement about a year ago, floating laminate over concrete. it was the cheapest stuff we found, about $1.09 a sf i think, it looks nice, but if you install it yourself, i suggest being very anal about the subfloor being absolutely level. in the places that i got the concrete leveled, it looks great, and its hard to pick out the seams. in high spots, where a plank can try to move up and down a bit, the seams start to show. its way better than carpet for cat hair. we have 2 dogs and 2 cats, and they bring in a lot of dirt, the laminate seems to almost repel dirt. sweeping gets it really clean easily. we've had water on it, not for too terribly long, but it hasn't been affected so far. just be careful with the subfloor, and its great stuff.
