There is a large difference in quality between products, manufacturers and product lines. I highly suggest you get samples, lots of samples, and test them for durablity and appearance.
When we built our home I tested about 70 samples. There was a brand called Jasper (if I remember correctly) that would dent or scratch if you dropped a cup on it-the products surface was incredibly soft. Others, like Bellawood products were almost scratch proof, and I couldn't dent it by dropping a hammer onto the sample. I also tested by sitting a leg of our heavy dining room table on the sample for a few days, and then pulling the sample out without lifting the table. Some dented and scratched, others were unscathed.
I suggest you stay away from laminate. While I'm sure they've come a long way, it's still easy to pick out a laminate floor and the repeating pattern. After all, they're nothing more than a photo of wood and they tend to scream "cheap".
Engineered hardwoods and real hardwoods will give you the best bang for the buck, and are far more attractive than laminates, and will increase your future resale value. Both can be done as floating floors, and if the right product is used, can be suitable for a kitchen. There are also some products, such as bamboo, that if I were in the market today I'd seriously consider.
The real key to noise is making sure the subfloor is solid. We glued and screwed our subfloors, and our floors are dead quiet when you walk over them. If I were to do an existing floor, once the old flooring was up I'd reinforce the subfloor by adding screws to the existing nails. When the new floor is installed make sure you use the correct underlayment-it will make a difference.
I put down all of our hardwoods and tile floors by myself in just over a week (about 1500 square feet of wood and 1000 tile). I've also put down engineered hardwood floors (the click lock floating system), and both nailed and floating floors are easy, just time consuming. If you are at all handy and have a few basic tools (including a table saw and a power miter saw) there is no reason why you can't do it.
