What do you look for in purchasing a recording?

I'm a member of a 100-or-so voice community choir in Washington, DC, and we're gearing up to do some recording in a couple of months - the Liturgy of St. John Chrysostom (in Georgian) by Zakharia Paliashvili. (This isn't a shameless plug - promise. That will be coming soon enough. ;D) We will also be publishing a critical edition of the score for sale.

A number of people have been talking about marketing this project primarily to the scholarly community - college music departments, religious studies departments, things of that sort. I think that would be a mistake, and that the project could easily have broader appeal. I've mentioned this in discussion with others, and they asked me to do a bit of marketing research, as it were. Hence this post. I hope y'all don't mind my picking your collective brains.

One of the major concerns is pricing. What's a good price? I know that I don't like to spend more than ten or twelve dollars on a CD of something totally unknown to me. Where do you draw the line - what's your high-end threshold? Does it change if the piece, or composer, is a known quantity? It does for me...to a certain extent. What about for a copy of the score - would that be of interest? At what price?

Another question that has come up has to do with selling a downloadable recording online. This is certainly something that I think would be viable. Would you be willing to pay for a download? (I'd suggest, if we do that, that we find some way of providing a downloadable copy of the liner notes as well.)

I've answered these questions myself, based on my own experience, in the various conversations I've had. But I'm more interested in what others might have to say about the subject, too.

(I hope this post is OK here - I couldn't think of any place else where it might fit.)
