Unfortunately CD-R`s for quite some time (not "on demand, you buy a CD and receive a CD-R) .... you have to be lucky to get a CD copy from "old stock" .... also here Steeplechase doesn`t give any guidance/info about this .... a rare chance to buy SteepleChase CD`s for sure was via the japanese Think! 45th Anniversary Series - with sensational transfer ....
