Egyptian Cotton Sheets?

I am in search of high quality 100% Egyptian Cotton sheets. I don't have time to actually go to a store and look for them because I live so far from any store that would sell top-notch sheets. So I have resorted to buying online. I already own a set of Egyptian cotton sheets but I have worn them out. lol I bought them at Kohls about 3 years ago. But I can't seem to find them now. I won't settle for less than 600 thread count and I only have a full size bed so that cuts down my options from most places. Any answers will be greatly appreciated!! Especially answers with some experience behind them!
