I have a polyester satin pillowcase and one that's silk. My silk case can't hold a candle to the poly one--it's much softer and gentler on my skin and curls.

I got mine from Amazon for about $20. My satin one was $5 from Bed Bath and Beyond. For the price, the satin one is fine, but the silk one is definitely superior.

ETA: the cases on Dharma are definitely cheaper than other places and they look nice. If $13 seems steep, think of it as an investment--my silk pillowcase has held up very nicely over the last year of washings.
