travertine looks nice,but make sure you get good pieces..it is natural so every piece will be different.alot of it has holes through it.ive did flooring for a couple years and have seen all diff. types.about 3 months back i had a guy who built houses,and had a connect with good prices for his personel house.it was so cheap he ended up returning close to 1500 squar feet....big pain.if you dont mind holes through it get the cheapest stuff you can get....ALSO it is VERY VERY britle.i can slightly tap it and it brakes....looks fantastic though,and is "hot" in the market right now
