Headway (the old books) on CD?

Hi! I teach ESL in Portugal. I'd like to know if anyone has the Headway takes (elementary, Pre-Int and Int) on CD? I have the tapes, but frankly, I'm tired of lugging a cassette player - it would be a lot easier to use a portable CD player, with small speakers, no? Anyone has those listening tracks on CD? BTW, I'm looking for the old Headway, not the new!
