I found a guy on ebay that sells them. I don't remember his username, but he's the only one on there that lists both the color and black heads. The last printheads I bought from him were I believe $195 for black and $235 for color. I've had as good a luck with these heads as the ones from cmykparts, and their also a ton cheaper than the Mutoh heads from GEI. I get about 6 months out of them, but I can buy 4 sets for what I was quoted for OEM.
