guys be very aware of printpartshop.com. i dealt with them re purchasing of 2 seiko heads. first the guy sells me one head, says it's brand new but has been opened "For Testing" and i trusted them. head was half blown up as soon as we installed it. then i get the tale of heads are not under warranty and all that BS. they are con artists, so PLEASE DON'T TRUST THEM and don't give them any business.
