I believe what your talking about is Thom Hogans E-manual about the Fuji S2... see http://www.bythom.com/s2guide.htm
. I don't think he'd be real happy or even FUJI, about e-bay versions..
It is real and available through FUJI as long as you register your S2, with Serial # at the FUJI site, link at Thom's site...!!! Look at the right side and go to the FUJI link!
