Dunno about relative value.
DigiTrad set out to be a songbook, and that's what it's remained. And DigiTrad started with the "free to all" concept and that's what it's remained. And always will. Of course, this requires a lot of time and a few idiots who are willing to do all the work in return for a warm fuzzy feeling.

Is the digital Child worth the money? To me it is--I'm buying a copy. As is Susan. What's a five-volume book worth, especially one with a severely limited audience? Paperback mysteries are selling for $11; hard-cover textbooks are selling for $75 or more. The argument about production costs after the initial work is done holds for hard copy as well as for digital copies. The digital Child, even at list price, is selling for the same price as the Dover reprint, and for a bit less than tha Loomis House edition in soft-cover (I am also buying the Loomis House edition--it supplements, rather than replaces the digital one IMO). Remember, the digital version also comes with an audio CD which, if sold separately would fetch $15-20.

It's certainly not for everyone. At the same time, it's certainly not a rip-off.
