is there a CD player that will slow down tempo without changing pitch?

Question

I am interested in finding a stand alone cd player, like a jambox, that I can use for my guitar students, for when they want me to teach them fast riffs. I know there are programs I can keep in my laptop but I don't want to lug around my laptop and a cd player. Is tempo shifting a feature on any ipod-type players?
