I'll second the positives about higher thread counts. Until I took a chance on a set of 500 and 700 TC sheets, I didn't see paying for anything more than 300 TC sheets. The difference is very apparent. Sheets last longer, feel better and more substantial, etc. Like the other reviewers, I won't go back to anything less than 500. $60 for a set of 500TC sheets is pretty good. I paid about the same at BB&Beyond for a set on clearance.
