We had pergo floors in one of our homes and I wouldn't do that again if I could help it, it has an overall 'cheap' feel/sound/appearance. It was already installed when we bought the place so what was done was done, but I'd never willingly go that route.

We have real hardwood floors on the first floor in our home now and they seem to have held up well in spite of how long they've been in place.

I'm seriously considering going with a whitewashed pine floor in a room upstairs but haven't gotten too far down that road just yet.
