Replacement Seats/Headrests?

I have an 1999 Rodeo with the regular "sport" seats (the ones with the head rests with a hole in the middle). The seats (especially the headrests) are'nt very confortable... Does anyone know how much the nicer seats and/or headrests are from the dealer? Or is anyone selling the upgraded seats/headrests? (leather not necessary, preferably gray)

Any info/leads would be helpful.

Don't go to the dealer. Way to much.
