I just bought 100% cotton, around 200 thread count sheets at Ikea for around $4 each. Can't beat that and the cotton fabric looks and feels pretty darn near close to LQS quality solids. I'm a fabric snob(admitted) and these sheets passed my snootie test. Can't beat the price, but I machine quilt ONLY.
Do a search for sheets on the search feature above. There have been a ton of threads about this.
