We are buying a one-story 1959 ranch-style home in Austin, Texas. The floors are 70% polished concrete (which is just the top of the slab). I want to add wood floors and our contractor is suggesting that we float the engineered wood floor on the slab.

We'll be adding wood to about 1100 square feet and will be adding cork to the kitchen area. I originally wanted to use real hardwoods, but have since learned that is a Bad Idea on a concrete slab in our area (and the height added by the install would be unworkable). So I'm looking at pre-finished engineered wood floors, which are much more stable with regard to moisture. The slab appears flat and is in good shape. The majority of the wood will be placed in a large L-shaped combo living/dining room area with a long straight run (about 40 feet), which will be the first thing you see when you come into the house.
Our contractor is suggesting that we float the engineered wood floor on the slab, which I believe would mean adding a moisture barrier, and then laying the wood directly on top of that, so that it isn't connected to the slab. This is quite a bit cheaper than laying down plywood, which is nice. However, I'm concerned that the floors will either be noisy or that there will be some other issue that will make me wish I had done the plywood install.
Long way of asking -- anybody had any experiences, positive or negative ("Don't do it!"), from floating engineered hardwoods on a slab? We're planning to stay in this house a *long* time, so want to do it right (and I'm mourning that we can't use solid hardwoods).
