Kenwood True-X drives out of production?

[http://forums.windrivers.com/cgi-bin/forum1/noncgi]

I've been looking everywhere trying to find another 72X Kenwood drive, but NOBODY seems to have them. Fry's doesn't, CompUSA doesn't, TechData doesn't, I can't find them on PriceWatch, and ComputerShopper.com lists only 1 retailer who has them (but that's a dead link).

Are they out of production or something?
