I agree. I think digital output is pretty much suspect when you start paying the big bucks. The people who buy fine art prints are usually pretty serious. More-so with the economic decline that is going on (and by that I mean less dot-com types running around simply buying "whatever" because the have too much money and want to look like they have culture). The fine art buyer will more likely be educated on the medium and not keen to plunk down $1,200 on something that will possibly fade in 10 years.
I mean you have to keep the stuff around until at least the artist dies in some tragic fashion so you can cash in!
