I have a choice between 4600 density, 90 ounce, PET polyester at $3.00 sq ft and 3600 density 70 ounce stainmaster nylon at 5.00 sq ft. No kids or pets, two adults, little traffic, about 700 sq ft to carpet. What is your recomendation gurus? I've heard you say nylon over and over, but I've also heard that density is the most important factor. Thanks for your help.

Since there isn't a general flooring forum and I am looking to replace my existng carpeting, this seemed the most appropriate place. My wife and I recently tried to sell our hosue and move farther south. After 4 months on the market, numerous open houses, price dropping, etc. (plus someone bought the house we had built down south), we pulled the house off the market for now (maybe try again next year if the economy is better). Anyway, everyone said the house showed well with the exception that the carpets (1st and 2nd floor) looked dirty. We have steam cleaned them ourselves and even had a professional come out about 3 years ago. I think they are just cheap builder's grade carpets (original carpeting, 8 year old house). Since this seemed to be the only area most people noted, I would like to change it before we put our house on the market again. And since we plan on moving, I don't want to spend a ton of money for something I may only get a year's worth of use out of. I have looked into carpeting, cork, etc. What is the least expensive, durable flooring that could be installed. First floor is slab on grade, second floor is a wooden subfloor. I have done some laminate flooring install, so I am not opposed (obviously since I am on this site) to something that is DIY. I don't want cheap stuff that I would have to repace in 6 months, but I also don't see spending $3k for something that I will not get to enjoy for more than a few months to a year. Any thoughts are appreciated. The area to redo is about 600 sf or so plus a stairway. Thanks, Neil
