Hey,
As I said, I do NOT think $20 is too high.
That version, esp being limited, is obviously for the true fans of the band.
Admittingly, you guys are one of many bands who I have heard, and liked most of what I heard, but not big enough of a fan where I would pay collector's prices for it. I am sure though there are 250 who will though.
I completely understand. I used to do a label myself that was 7"s only.
You would have to charge at least $5 or more per 7" to even remotely make back all the costs, down to the recording, esp if you only press 500 or less, which I did.
